My apologies if this has been posted earlier or more than just a few times; I did a quick but not deep search. The following text block has been cut and pasted from the online passport application site, Boise, Idaho, but it's the same boilerplate just about everywhere. The info at Dept of State site has not been updated since July 21, 2021.
The State Department issued a nation-wide alert July 21, 2021
concerning passport application delays related to COVID-19.

County Recorder’s Office. Expedited service (an additional $60) may
