Due to a planned network upgrade, all Stack Exchange sites will be read-only for a maximum of two hours this week. The first window was Tuesday, September 28, 2021 between 9 PM (21:00) and midnight (23:59) US/Eastern (a.k.a. NYC-time), but that upgrade attempt failed. The second window will be Thursday, September 30, 2021 (also between 9 PM and midnight US/Eastern). During this window, the site will be read-only for up to two hours, likely less.
