Investigating alerts for degraded room service

This incident has been resolved. Between 19:45 and 20:00 UTC, US West and US Central experienced intermittent degradation in Room Service and SIP performance. We rerouted traffic and performance has returned to baseline as of 22:00 UTC. We will follow up with a postmortem, which will include further details regarding scale and scope.

We have applied a mitigation to the affected regions and are now monitoring to ensure that performance signals return to baseline. We are still working on determining impact (including how users can determine if they were affected) and will share those details as soon as possible.

We are currently investigating automated alerting which triggered for degraded Room service performance in the US West and US Central regions beginning around 19:45 UTC. We are working to determine if there is any customer-facing impact. If there is impact, we don't currently have reason to believe that it is widespread.

We will update again within 30 minutes.
