When did PSA close value in 2021?

Can someone please remind me when PSA closed bulk in 2021? The backlog seems to be moving along quickly lately. My 4/19/21 value order just hit QA2. Thanks!

In early March 2021 they raised prices then at the very end of the month (I want to say March 29th or 30th?) they shut down value/regular/express submissions altogether
