Please report any issues on MSO.  The user-visible read-only was 11:26AM-12:27PM (ET)… almost exactly one hour.  Thank you for your patience!

https://meta.stackexchange.com/questions/370872 is starting soon. Only SEDE will be affected, if there is any user-visible disruption at all.

This is about to begin.  https://meta.stackexchange.com/questions/371236

The site is back! It took a lot longer than expected (our apologies) but we decided to take the safe/slow route rather than take some risks. Tomorrow’s maintenance window is still required as planned. Thank you all for your patience. This is going to be a fun retro to write!
