Priority Colo staff will also be onsite, replacing the fans in each distribution router with new high speed fan trays in preparation for the new supervisor cards.

Just an update this notice:

The maintenance notice originally sent to customers on Monday said "EST" for the time zone. A customer helpfully reminded me today that we're in EDT timezone technically. This maintenance (and any time we say Eastern Standard Time in general) should refer to the local timezone, including daylight savings time as applicable.

I hope this doesn't create any confusion.
