Caches for the StashCache federation. There are dozens of caches, not all of them are affected by every downtime.

APEL reporting reports WLCG usage gathered in the OSG to the WLCG. The OSG is only required to send data at the beginning of each month. If this is down, and it's not at the beginning of the month (within 1-2 days), then we can always send the data later. If it is in the beginning of the month, then this is critical for WLCG usage reporting.
