Scheduled - Between Sunday 2021-07-25 1800 UTC and Sunday 2021-07-25 1900 UTC, EU customers may experience a series of brief interruptions to the following features: sending/receiving messages, calendar, access to the app. This is due to planned maintenance work required on our core database services.

What is the impact?
During the window, sending/receiving messages or accessing the app may be degraded or unavailable for a few minutes. The delivery of some messages may be delayed.

Why are we doing this?
Some of our database clusters need to be restarted during the maintenance window while we perform an important database upgrade. We are starting to do this type of work during the weekends to minimize disruption to customers.

What will the exact experience be for our customers during the change?
Developers trying to use the API: They may receive a 503 "service unavailable" or 500 error in their response during the brief interruptions. This should be resolved after a few minutes.

Teammates already logged in: They may receive a Front error message in their browsers and will have limited functionality for a few minutes.

Teammates trying to load the app: They may receive a generic 503 "service unavailable" or a 500 error message in their browser during the brief interruptions. This should be resolved after a few minutes.

What will happen to messages that are scheduled to be sent during this time?
Some messages may be delayed for a few minutes.

What will happen to inbound messages?
They will be queued up and processed/delivered once the affected features are back up.
