Our Scheduled Maintenance notification dates for our region/instance names, does not line up with the Bi-monthly updates listed on the web page. Can someone explain what the actual process is? thank you.

I see updates on the web page for Jul 25, Sep 25, Nov 25 which suggests all updates are done bi-monthly yet our Scheduled maintenance e-mails show the following dates, which suggest not all systems are updated every other month.

test 8/6/25, dev 9/25/25, test 9/25/25, dev 9/29/25, prod10/1/25, test 12/1/25, dev 12/2/25

It would be so much cleaner if the bi-monthly updates were done on a fixed schedule, would make this more predictable for planning and testing of the updates. so for example if the Nov 25 update was done on the dev and test systems the beginning of the month, so we had a window of a week or two to test, before it would be installed to production.
