We've scheduled an essential maintenance window on Plain, during which we will upgrade our main database cluster.

When: Wednesday, 2nd October at 6AM to 8AM UTC.

• New York (EDT): 2AM

• Berlin (CET): 8AM

• California (PDT): 11PM on the 1st of October

• Sydney (AET): 4PM

What to expect during this time:

• There will be no access to app.plain.com

• The API will be unavailable

• Webhooks will not be sent

• Notifications will not be sent

Rest assured:

• There will be no data loss: all inbound emails, Slack messages, MS Teams messages, Linear issue updates and data from importers will be safely queued and processed after the downtime. No information or customer messages will be lost.

• SLA tracking won't stop during downtime. Breached SLAs during this maintenance window will trigger an alert right after the maintenance is over.

• Flexible timing: we've set a 2-hour window as a precaution, but we are working hard to minimize the actual downtime

What you need to do:
We strongly recommend planning around this maintenance window with your team to reduce the impact on your internal processes. If you use our API, make sure your code gracefully handles HTTP 503 errors during this time.
