Probably more disruption from the outages earlier today. We will continue to send beam to Hall C and keep an eye on the dump screen which is still working

Their initial complaint was the U wire sigma on 3H07A was more than 300 um but I reassured them that this was not a wire which we pay heed to. Their other complaint was the shoulder on the 3H07B harp swipes. We intend to send some CW in the main machine with the Hall C target out to suss out where we might be scraping, but are down for the unresolved dump cooling alarms and waiting to hear back from facilities.

The following websites and apps were inaccessable during the computer center outage today:

All electronic logs
PD shift Plans
JAM
SRM
Downtime Manager
When-to-Work
ePass system
Costpoint
No access to Ops procedures or Administrative documents (AOD, ASE, etc.)

PSS iFix screens malfunctioned (may have been caused by the outage, but not sure.)

After ACE webservices were rerouted to the fallback host, Ops PRs still would not work from either the web app or from JELI.
