Briefly Unavailable for Scheduled Maintenance? The Real Fix (2026)

https://www.ahosting.net/blog/briefly... When WordPress shows "Briefly unavailable for scheduled maintenance" after you click Update, the usual advice is to find the hidden .maintenance file and delete it.

This video walks through the WordPress 7.1.2 source: what the .maintenance file contains, how the ten-minute expiry works, how to check with curl whether the server or a cache is showing the notice, why Update all shares one timer, why "Another update is currently in progress" is a separate database lock, why updates get interrupted on shared hosting, and how to put back a plugin an interrupted update moved aside. 00:00 Briefly unavailable for scheduled maintenance: what it means 00:45 What is inside the .maintenance file WordPress writes? 00:57 How long does WordPress maintenance mode last? 01:13 Site still in maintenance mode after 10 minutes?
