Impact from the ongoing AWS us-east-1 outage

This incident has been resolved.

AWS has resolved their incident. We're continuing to run the same call servers in us-east-1 as we were before the incident started, but we're still routing the majority of US traffic through us-west-2. We plan to return things to normal tomorrow.

AWS is continuing to address issues in us-east-1. We're still seeing normal activity levels across our APIs and call servers for this time of day, so we have no reason to believe that any your customers' calls are actually being affected.

Part of AWS's mitigation efforts involve limiting the rate at which we can start new call servers. Out of an abundance of caution, we're temporarily removing us-east-1 from our list of available regions for new call sessions. This means your users will likely connect to a call through us-west-2 instead. This failover happens automatically and transparently, and you don't need to do anything.

We've already scaled up call servers in us-west-2 to handle the increase in sessions. We'll keep you posted as we continue to monitor the situation.

AWS is addressing an issue with DynamoDB that is causing problems with many of their services in us-east-1. We have seen issues loading the dashboard and docs sites, and for a few hours we've been unable to log in to Statuspage to update this site. We're sorry about that delay.

Up until a few minutes ago, our metrics suggested that core call functionality wasn't being impacted. We just saw a small number of call failures in us-east-1, though. We're continuing to monitor the situation and do what we can to minimize this outage's impact on you and your customers.

We'll post more information here as we have it.
