Servers are down again worldwide, Google’s official response: due to internal technical failures

On December 15th, on Monday, local time in the United States, Google servers once again went down globally. However, the company has found the culprit responsible for the paralysis of dozens of services, that is, due to internal technical failures. server CPU


On Monday morning, almost all of Google's major applications were unable to go online, including YouTube and Gmail, resulting in hundreds of millions of users unable to access key services. The company said that the downtime was due to an internal storage quota issue (similar to a mobile phone notifying users that storage space was about to run out), which caused the authentication system used to log in to user accounts to malfunction.

A Google spokesperson said in a statement: "At 3:47 AM Pacific time, Google’s authentication system was interrupted for approximately 45 minutes due to internal storage quota issues. During this period, services that required users to log inexperienced a high error rate. The authentication system issue was resolved at 4:32 am Pacific time. All services have now been restored. We apologize to each affected user, and we will conduct a thorough follow-up review to ensure that this issue will not recur in the future. "

The downtime had a profound impact because other Google services such as Google Maps, Calendar and its cloud storage Google Drive application were all listed as affected by the downtime on the company's own status dashboard. Many of Google's affected services are the most widely used services in the world. For example, YouTube has more than 2 billion active users, and Gmail is the world's most popular email platform with more than 1.5 billion users.

Service monitoring site Down Detector also reported that users also had problems accessing the Google App Store and Google Meet and Hangout communication tools. During the service downtime, many people shared their disappointment on this massive and rare service interruption on social media, and the technology giant quickly became the focus of online discussion.

In response to this incident, Adam Leon Smith, head of the Special Interest Group for Software Testing of the Chartered IT Society (BCS), emphasized the problems experienced by users of Google's smart home products during service outages, and Said that this incident shows how highly dependent the world is on a few technologies.

He said: “People are sitting in the dark and can’t open the Google homepage. Neither of my two recent meetings can use the designed slides because they are stored in Google Slides. Our reliance on technology has become stronger, but in Spending on reliability, testing, and quality has not kept pace. Today, many companies will re-examine their service level agreements (SLAs) with Google and realize that their businesses are relying on things that are completely out of their control."

Alan Woodward, a cyber security expert at the University of Surrey in the UK, said: “We now basically host all services to cloud services and third-party providers. Although they are very flexible, no one can Complete immunity, a small point of failure may affect millions of people. We are all too used to relying on the Internet. As the epidemic spreads, we all work from home and try to use these services 24/7. This impact is being Infinitely zoom in."

This is not the first time a Google service has a downtime, or even the first time this year. When the United States was blocked due to the new crown pneumonia epidemic at the end of March this year, Google's Gmail, YouTube, Hangouts, and Docs were all inaccessible. Even the Google search engine had service abnormalities. At that time, the demand for home office was soaring. Google officially stated that this was a network failure, denying that it was related to insufficient network capacity.

In August, Google services suffered several hours of global downtime. Millions of G Suite users faced service interruptions for Gmail, Google Drive, Google Chat, Google Meet, Google Groups, Google Docs, Google Keep and Google Voice. The incident affected most parts of the world, including Japan, Singapore, India, Europe, parts of the United States, China, Southeast Asia and the Gulf region, and Australia. Google managed to restore the service only six hours later and did not explain the cause of the downtime.

The most recent global outage occurred on September 24. At that time, Google's website, Gmail, YouTube, Docs and other services were interrupted, and user login was denied. The company’s senior vice president of technology infrastructure, Urz Holzle, revealed the reason: “A server pool that routes traffic to the back end of the application has crashed, and users in that pool have experienced downtime.”

AMD's GPU technology enters the mobile phone chip market for the first time

In addition to the release of the Exynos2100 processor, Samsung also confirmed a major event at this Exynos event, that is, the custom GPU that they have worked with AMD for many years will soon appear and will be used on the next flagship machine. The current Exynos2100 processor uses ARM’s Mali-G78GPU core with a total of 14 cores, so the GPU architecture developed by Samsung will be the next Exynos processor, and the GPU will be the focus. This is probably the meaning of Exynos2100’s GPU stacking. The key reason. Dr. InyupKang, president of Samsung’s LSI business, confirmed that the next-generation mobile GPU in cooperation with AMD will be used in the next flagship product, but he did not specify which product. Samsung is not talking about the next-generation flagship but the next one, so it is very likely that a new Exynos processor will be available this year, either for the GalaxyNote21 series or the new generation of folding screen GalaxyZFold3. In 2019, AMD and Samsung reached

Apple and Intel want to join the game, what happened to the GPU market?

Intel recently announced that it will launch Xe-LP GPU at the end of this year, officially entering the independent GPU market, and will hand over to TSMC for foundry. At the 2020 WWDC held not long ago, Apple also revealed that it is possible to abandon AMD's GPU and use a self-developed solution based on the ARM architecture. It will launch a self-developed GPU next year. What happened to the GPU market? Why are the giants entering the game?    Massive data calls for high-performance GPU    Why has the demand for GPUs increased so rapidly in recent years? Because we are entering an era where everything needs to be visualized. Dai Shuyu, a partner of Aiwa (Beijing) Technology Co., Ltd., told a reporter from China Electronics News that visualization requires a large amount of graphics and image computing capabilities, and a large amount of high-performance image processing capabilities are required for both the cloud and the edge.    Aiwa (Beijing) Technology Co., Ltd. is an enterp

NVIDIA officially launches RTX 30 series mobile graphics cards

In the early morning of January 13, NVIDIA officially launched the RTX30 series of mobile graphics cards at the CES2021 exhibition. Ampere-based GPUs have also reached the mobile terminal, mainly including RTX3080, RTX3070 and RTX3060 models. In addition to improving game performance, the RTX30 series of mobile graphics cards have twice the energy efficiency of the previous generation, and support the third-generation Max-Q technology, mainly supporting DynamicBoost2.0 dynamic acceleration technology, WisperMode2.0 noise control, ResizableBAR (similar to AMD’s SAM technology) and DLSS. The third-generation Max-Q technology uses AI and new system optimization to make high-performance gaming laptops faster and more powerful than ever. These technologies include: ·DynamicBoost2.0: The CPU and GPU powers of traditional gaming notebooks are fixed, while games and creative applications are dynamic, and the requirements for the system will vary with the number of frames. With DynamicBoost2.0,
