+We wanted to make you aware that on **Friday, February 14 at 2:00pm PST (5:00pm EST, 22:00 UTC)**, Read the Docs will be having a scheduled downtime of approximately 2 hours.
+This will impact both **Read the Docs Community** and **Read the Docs for Business**.
+We expect the downtime to only last for 15-30 minutes, but we are scheduling a longer window to account for any unforeseen issues.
+
+During this maintenance window, public documentation will continue to be online but new documentation builds will not trigger and the Read the Docs dashboard will be unavailable.
+New builds and webhooks will begin processing once the maintenance is over.
+
+To ensure minimal impact for our users, we are performing this upgrade during a Friday afternoon which is one of our lowest usage periods.
+This maintenance window is for a required database version upgrade to PostgreSQL from our hosting provider, which we couldn’t perform in place.
+While these kinds of things do happen from time to time, we haven’t had a scheduled downtime on Read the Docs in a few years. Doing this helps us ensure that our services perform well and have up-to-date security.
+
+Thanks for your understanding of this maintenance downtime.

+Read the Docs team
