ThousandEyes Internet Outage Map picked up the Dec. ThousandEyes alerts were coming in across many different Amazon sites and services, and our real-time Internet Outage Map was blinking big purple circles where AWS web servers were failing to respond to users. December 7, 15:32 UTC – The Outage Beginsīy about 15:40 UTC, within minutes of the start of the outage, it was clear that something big was happening within AWS. #NETWORK UNREACHABLE AMAZON SERVICES PLUS#In this post, we’ll unpack both phases of the initial incident plus take a look at the separate December 10th incident, and highlight critical lessons that can help organizations have better outcomes when the next, inevitable outage comes their way. Then, on Friday, December 10th, yet another large scale outage impacted various AWS services, with AWS servers returning errors for over an hour. The impact of this second wave of the Tuesday outage lasted for over 7 hours, not fully resolving until approximately 0:44 UTC (4:44 pm PT). While site loading appeared to mostly normalize by 16:50 UTC (8:50 am PT), soon after, ThousandEyes observed AWS API service failures that caused API transactions to experience dramatically higher completion times or simply time out. The first phase of the December 7th outage began at approximately 15:35 UTC (7:35 am PT), when multiple Amazon sites and services began to show significant performance degradation. ThousandEyes observed the entirety of both incidents, the first of which occurred over two overlapping phases, each with slightly different characteristics. While the goal of the Internet is to decentralize and make network services resilient, the heavy use of cloud services across all industries still reveals the fragility and increasing complexity of today’s digital ecosystem. Then, on Friday, December 10th, another ~hour-long ‘aftershock’ service disruption occurred, though to much less attention than the original Tuesday incident. The incident affected everything from home consumer appliances to various business services. On Tuesday, December 7, 2021, multiple Amazon services and other services that rely on them were impacted by an outage event that in total, lasted more than 8 hours. The following is an analysis of the outage, which is updated periodically as we had more information to share. I have no such problems with other Linux distributions but only with CentOS.On December 7, 2021, AWS experienced a prolonged outage that impacted users in various regions across the globe. In the mean time I can ping assigned IPv6 locally.

In the mean time it does work with ping. I've also deployed clean CentOS instances to reproduce the problem, but it's still there and unresolved. #NETWORK UNREACHABLE AMAZON SERVICES MANUAL#I've followed with the manual for my current CentOS 7 workstation to migrate it to IPv6. Just to confirm that I've tried everything. Probably somebody can help me since AWS forum threads, nor googling weren't successful. I'm to figure out a problem with IPv6 connectivity.
