I feel bad for the people working on this. It sounds like desperation is increasing.

From the 10:11:39 PM UTC update:

Current status: We're continuing to pursue all available pathways to restore service, as our actions taken thus far have not provided the anticipated relief. Our investigation has found that a core process on the affected servers is becoming overwhelmed, which causes the servers to stop responding and contributes to the capacity loss.

To validate a potential recovery approach, we're fully isolating a portion of our service infrastructure, restarting the affected components, and gradually reintroducing traffic to confirm our services remain stable before applying this approach more broadly. We're also analyzing traffic patterns across our entire service infrastructure and evaluating whether isolating traffic within each region may allow affected regions to recover independently.

From the 9:41:46 PM UTC update:

Current status: We're continuing to work through restarting and validating the affected servers to safely return them to service, and we're exploring opportunities to expedite this process. In parallel, we're assessing whether reverting the small number of recent configuration updates we identified could help accelerate recovery.

From the 9:01:14 PM UTC update:

Current status: We've validated an alternative health check method on a subset of affected infrastructure, which allowed the servers in that subset to successfully return to service, and we're now applying this change more broadly. We're also preparing an automated recovery process to continually detect and restart unresponsive servers, to help keep them in service while this change progresses. Additionally, our review of recent changes has identified a small number of configuration updates that we're investigating as potential contributors to the issue.

From the 8:44 PM UTC update:

Current status: While validating the targeted change, we found that many of the affected servers have become unresponsive, which is preventing us from confirming whether the change is effective. We're restarting these servers so they can come back online with the change in place, and we're applying the same approach to additional affected portions of our infrastructure to validate the results more broadly.

Previous Status: While we haven't identified any recent changes that correlate with the start of impact, our investigation indicates the failed health checks may originate from a specific component on the affected servers that's responsible for processing them. We're deploying a targeted change to bypass this component on a subset of servers to validate whether this restores availability, and we've taken steps to prevent additional servers from being removed from service while we work to return the affected servers to service. We're also investigating why affected servers are experiencing elevated processor usage while handling requests.

Working in reverse-chronological order here:

So much for seeming hopeful.

From the 12:08:53 AM UTC update:

Current status: While the servers we've returned to service initially remain healthy, we've observed that they can become unresponsive again once they begin receiving traffic. We're analyzing diagnostic data from these servers with our networking and platform experts to determine what's triggering this behavior.

Building on the protective traffic management measures we've implemented, we're also temporarily limiting which types of traffic can reach the affected infrastructure in specific locations. This will help us determine whether a particular type of request is contributing to the impact and allow us to restore service incrementally. Additionally, we're rebuilding a subset of affected servers using a previous software configuration to validate whether this prevents them from becoming unresponsive, and we'll expand this approach to additional servers if we observe positive results.

The 11:05:31 PM UTC update is is the first since the outage began that feels hopeful.

From the 11:06:31 PM UTC update:

Current status: We've begun returning a portion of the affected servers to service, and they're remaining stable so far. We've also shifted traffic and connections to alternative pathways wherever possible and have observed limited recovery in some regions.

We've streamlined our recovery process to expedite returning the remaining affected servers to service. To further support recovery, we're implementing protective traffic management measures in a specific location to reduce load on the affected infrastructure, and we'll expand these measures to additional locations if we observe positive results. As capacity is restored, users may experience a gradual recovery as their clients reconnect to the service.

Sounds like nobody knows how their own systems work anymore.

their employer brought me agent swarms supposed to take over my php-serving machines. whatever this is, I don't feel sorry for them.

So the thundering herd wins again

Ugh. There's some yahoo from NewsNation on WGN Radio right now saying this is because of the Chinese, and obliquely linking it to Nvidia.

Reddit-level speculation.

they are furiously typing at their agents hoping they can figure out what to do. Getting glimps of hope everytime claude says "I found it." only for their hopes to be crused at "Turns out ...". The clown show at Microsoft is surreal.
