Major Revelation: Amazon Web Services Outage Highlights UK Government’s £1.7 Billion Reliance on Tech Giant

Amazon’s CEO Andy Jassy wore a broad smile while meeting Keir Starmer in the gardens of Downing Street to announce a £40bn investment in the UK this past June. Starmer shared his enthusiasm, stating, “equally passionate”. He remarked, “This transaction demonstrates that our transformation strategy to attract investment, stimulate growth, and enhance people’s financial well-being is succeeding.”

However, just four months later, the company faced a massive global outage on Monday that halted thousands of businesses and underscored its reliance on Amazon Web Services (AWS), the cloud computing platform utilized by the British government.

Data gathered for the Guardian indicates that the UK government is increasingly dependent on the services of U.S. tech giants. These companies have come under fire from trade unions and politicians for their working conditions in logistics and online retail.

Since 2016, AWS has secured 189 contracts with the UK government valued at £1.7bn and has billed approximately £1.4bn during this timeframe, according to data from public procurement intelligence firm Tassel.

The research group reported: “Currently, 35 public sector authorities utilize AWS services across 41 contracts totaling £1.1bn. The primary ministries involved include the Home Office, DWP, HMRC, the Ministry of Justice, Cabinet Office, and Defra.

Tim Wright, a technology partner at law firm Floodgate, noted that the Financial Conduct Authority (FCA) and Prudential Regulation Authority (PRA) have consistently warned about the risks associated with concentrating cloud services for regulated enterprises.

“Recent efforts by the Treasury, the PRA, and the FCA to impose direct oversight on ‘significant third parties’ aim to mitigate the risk of outages like those faced by AWS,” he said. “However, until we see substantial diversification and the establishment of sovereign clouds, the UK government’s approach contradicts the resilience principles that regulators advocate for.”

The House of Commons Treasury Committee has reached out to Chancellor of the Exchequer Lucy Rigby to inquire why Amazon wasn’t classified as a “significant third party” within the UK financial services sector, a designation that would have subjected the tech giant to regulatory scrutiny.

Committee Chair Meg Hillier noted that Amazon recently informed the committee that its financial services clients rely on AWS for “resilience” and that AWS offers “layers of protection.”

This week’s outage impacted over 2,000 businesses around the globe, leading to 8.1 million reports of issues, with 1.9 million in the U.S., 1 million in the UK, and 418,000 in Australia, according to internet outage tracker Downdetector.

Only HMRC confirmed it was affected by the outage, stating customers were “experiencing difficulties accessing our online services” and recommended they call back later due to busy phone lines.

While many websites restored their services after a few hours, some continued to experience problems throughout the day. By Monday evening, Amazon announced that all cloud services had “returned to normal operations.”

Trade unions have long questioned whether Amazon should be excluded from government contracts because of its reputation for subpar working conditions in its large warehouses.

Andy Prendergast, national secretary of the GMB union, stated: “Amazon has a dismal record regarding fair treatment of workers. Shocking conditions in their warehouses have resulted in emergency ambulance calls, with employees claiming they are treated like robots, forced to work until exhaustion, all while being compensated with poverty wages until they strike for six months.”

“In this context, wasting nearly £2 billion of public funds is deplorable.”

AWS has not provided a comment. A spokesperson from Amazon’s fulfillment centers stated that the “vast majority” of ambulance calls at their facilities are not “work-related.”

Webb’s revelation of hydrogen sulfide in the atmosphere of a hot Jupiter

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have detected trace amounts of hydrogen sulfide in the atmosphere of the Jupiter-sized exoplanet HD 189733b.

HD 189733b is a hot gas giant with a hazy atmosphere composed mostly of hydrogen that lies about 63 light-years away in the constellation Vulpecula.

The planet is discovered It was discovered in 2005 by astronomers using two telescopes at the Observatory of Haute-Provence.

HD 189733b is just 1.2 times the size of Jupiter, but it orbits its parent star, HD 189733, very closely, completing one revolution around the star every 2.2 days.

“Hydrogen sulfide is a major molecule that we didn't know existed. We predicted it would be there, and we know it's on Jupiter, but we'd never actually detected it outside the solar system,” said Dr Guangwei Hu, an astrophysicist at Johns Hopkins University.

“Although we're not looking for life on this planet because it's too hot, the discovery of hydrogen sulfide is a stepping stone to finding this molecule on other planets and improving our understanding of how different types of planets form.”

“In addition to detecting hydrogen sulfide and measuring the total amount of sulfur in HD 189733b's atmosphere, we also precisely measured the main sources of oxygen and carbon on the planet: water, carbon dioxide, and carbon monoxide.”

“Sulfur is an essential element for building more complex molecules, and like carbon, nitrogen, oxygen and phosphate, scientists need to study it further to fully understand how planets are built and what they're made of.”

The Webb probe will give scientists new tools to track hydrogen sulfide and measure sulfur on gas giants outside our solar system, just as they have detected water, carbon dioxide, methane and other important molecules on other exoplanets.

“Let's say we study another 100 hot Jupiters and they're all enriched with sulphur. What does that say about how they came into being and how they formed differently compared to our Jupiter?” Dr Fu said.

The new data, delivered by the Webb Telescope at unprecedented precision and in infrared wavelengths, also rule out the presence of methane in HD 189733b's atmosphere, refuting previous claims that the molecule is abundant in the atmosphere.

“We thought the planet would be too hot for high concentrations of methane to exist, but it turns out that's not the case,” Dr Fu said.

Astronomers also measured Jupiter-like levels of heavy metals, a discovery that could help scientists answer questions about the correlation between a planet's metallicity and its mass.

“Low-mass ice giants like Neptune and Uranus contain more metals than gas giants like Jupiter and Saturn, the largest planets in the solar system,” Dr Fu said.

“High metallicity suggests that Neptune and Uranus accumulated more ice, rock and other heavy elements compared to gases such as hydrogen and helium early in their formation. Scientists are testing whether this correlation also holds true for exoplanets.”

“This Jupiter-mass planet is very close to Earth and has been very well studied. Now, our new measurements show that this planet's metal concentrations provide a very important anchor point for studies of how a planet's composition varies with its mass and radius.”

“This discovery supports our understanding of how planets form after the initial core is formed, creating more solid material that is then naturally enriched with heavy metals.”

The Revelation of Why Some Individuals Have Greater Resistance to the Novel Coronavirus

By intentionally exposing people to the coronavirus that causes COVID-19, scientists have been able to understand why some people appear to be immune to infection.

As part of the first human COVID-19 challenge study conducted in 2021, an international group of researchers looked at 36 healthy people who had not tested positive for SARS-CoV-2 and had not been vaccinated.

The ancestral SARS-CoV-2 strain was sprayed into their noses. Nasal and blood samples were taken from 16 of the participants before exposure and then six to seven times over the next 28 days. All were also tested for SARS-CoV-2 twice daily.

Participants were split into three groups, team members said. Sarah Teichmann The study was conducted at the Cambridge Stem Cell Institute. In one group, six participants tested positive in both daily tests for more than two days and also had symptoms. In another group, three participants tested positive in one of two daily tests but not in the other and did not have symptoms, but for less than two days. In the final group, seven participants consistently tested negative for coronavirus.

In total, the researchers sequenced more than 600,000 blood and nasal cells across all subjects.

In the second and third groups, the researchers found that participants were producing more interferon (a substance that helps the immune system fight infection) in their blood in front of the nasopharynx (the top of the nose at the back of the throat where the nasal samples were taken). The interferon response was actually higher in the noses of participants in the second group than in the third group, Teichmann says.

These groups also did not have active infections within the immune cells T cells and macrophages, team members say. Marko Nikolic At University College London.

The results showed that high levels of gene activity HLA-DQA2 Exposure to SARS-CoV-2 helped prevent persistent infection.

Nikolic hopes that this discovery will improve understanding of the cellular responses involved in preventing COVID-19 and aid in the development of vaccines and treatments.

“With its carefully controlled design and real understanding of 'time zero' when infection occurs, this study will serve as a unique resource of previously uninfected SARS-CoV-2 participants to measure subsequent immune responses,” the study said. Jose Ordovas Montanez Harvard Stem Cell Institute

But most people have been exposed to “a true mosaic of SARS-CoV-2 variants,” not just the ancestral variant used in the study, so the results may not reflect cellular responses outside the testing environment, he says.

Shocking Revelation: The Dark Truth behind Mayan Human Sacrifice

The ancient Maya civilization of Central America has fascinated scholars for centuries with its incredible astronomical calendar and magnificent step pyramids.

But alongside their glorious culture, they are also associated with another dark cultural phenomenon: human sacrifice. And according to recent research, very It's certainly dark.

New findings from an analysis of ancient DNA from the ancient Maya city of Chichen Itza suggest that many of those sacrificed were children, including a high proportion of identical twins.

Published in a journal NatureThe study looked at human bones found in a xultun, or underground cistern, located near a large sinkhole known as the Sacred Cenote.

Radiocarbon dating (when scientists use decaying radioactive carbon to estimate the age of organic remains) suggests that the chultun was used between the early 7th century AD and the mid-12th century AD.

“The only people in Chultung were children between the ages of three and six.” Dr. Rodrigo BarqueraThe lead author of the study is BBC Science Focus“Until now, we haven't had the opportunity to report the sex of these individuals because when they are that young, you can't determine their biological sex based on the bones alone.”

Moving quickly on from how bleak a hole filled with 100 children looks, DNA evidence revealed that all 64 people tested were male, and about 25% were close relatives, including two sets of identical twins.

The chance of having identical twins is about 1 in 250, so two sets of male twins in such a small sample size is unusual.

Barquera explained that twins had a special meaning to the Mayans because one of their most important myths involves heroic twins who defeat the king of the underworld.

The team believes that unlike other sacrificial rituals that were intended as offerings, the sacrifice of identical male twins may have been undertaken to honour the existence of hero twins.

While that's not great news for identical twins in Mayan culture, as Barquera says, it would have been a huge honor for the family: “It was more like, 'Wow, the gods or the powers that be have chosen us to be the guardians of these children who will one day participate in this magical ceremony.'”

“We know this because the site has been there for over 500 years. This isn't something that happened once or twice; it's been a widely held belief for at least five centuries,” he said.

Next, Barcela and his team hope to confirm their findings by comparing them with other similar archaeological sites.

Black Holes’ Eating Habits: A Surprising Revelation

An imaginary diagram of the interstellar medium distribution of active galactic nuclei based on current observation results. Dense molecular gas from the galaxy flows along the disk’s surface toward the black hole. The energy generated by the high temperature of the material accumulated around the black hole destroys molecular gas, converting it into atoms and plasma. Most of these multiphase interstellar mediums are jets flowing outward from the galactic center (mainly plasma jets occur directly above the disk, and mainly atomic and molecular jets occur at an angle). However, it turns out that most of the particles flow back into the disk like a fountain. Credit: ALMA (ESO/National Astronomical Observatory of Japan/Nuclear Astronomical Observatory), T. Izumi et al.

Recent advances in astrophysics have led to groundbreaking observations of gas flows around supermassive black holes. These observations were made with great detail. light years Important insights into the behavior of these giant universes have been revealed. Remarkably, the researchers found that while large amounts of gas are attracted to these black holes, only a small portion (about 3 percent) is actually consumed. The remaining gas is ejected and recycled back to the host galaxy.

Not all substances fall into this. Black Hole It is absorbed, but some is excreted as effluent. However, it has been difficult to measure the ratio between the amount of material that a black hole “eats” and the amount that it “falls into.”

An international research team led by Assistant Professor Takuma Izumi of the National Astronomical Observatory of Japan is developing the Atacama Large Millimeter/Submillimeter Array (alma telescope) Observe a supermassive black hole in the Circus Galaxy, 14 million light-years away in the direction of the constellation Circus. This black hole is known to be actively feeding.

The plasma outflow proceeds almost perpendicular to the disk. Credit: ALMA (ESO/National Astronomical Observatory of Japan/Nuclear Astronomical Observatory), T. Izumi et al.

ALMA’s role in solving the mystery of black holes

Thanks to ALMA’s high resolution, the research team was able to measure the inflow and outflow around a black hole for the first time on a scale of several light years. By measuring the flow of gases in different states (molecules, atoms, and states), plasma) The team was able to determine the overall feeding efficiency of the black hole and found it to be only about 3%. The researchers also confirmed that gravitational instability is driving the influx.

The analysis also showed that most of the ejected outflow was not fast enough to escape from the galaxy and be lost. They are recycled into the perinuclear region around the black hole and begin falling slowly towards the black hole again.
