This issue is resolved. Between 13:30 and 17:30 UTC, incoming emails took longer than usual to appear in Plain, in some cases more than an hour. This was caused by a delay at our third-party inbound email provider, who has since deployed a fix. Delayed emails were not lost, and all of them should now be in Plain. Other channels and the web app were not affected. You don’t need to do anything. Sorry for the disruption.

Our upstream email provider has put a fix in place and is monitoring. We're still receiving the backlog of incoming emails that were delayed since around 13:30 UTC, so some emails may still arrive late while it clears, but none have been lost. We'll share another update within 30 minutes.

Our upstream email provider is still delivering the backlog of incoming emails that were delayed since around 13:30 UTC. Since 16:30 UTC we've been receiving these emails at a faster rate, so the backlog is clearing more quickly. Some delayed emails are still arriving late, but none have been lost. We'll share another update within 30 minutes.

Our upstream email provider is delivering emails to Plain again, and we're now receiving the backlog of emails that were delayed since around 13:30 UTC. Some delayed emails are still arriving late while this backlog clears, but none have been lost. We'll share another update within 30 minutes.

We've identified that these delays are caused by an issue with our upstream email provider. Incoming emails are currently taking more than an hour to show up in Plain. They're arriving late, not lost, and the backlog will clear once our provider recovers. We'll share another update within 30 minutes.
