A fiber cut between the University of Michigan and Chicago happened yesterday and, because of our network resiliency, connectivity for MOST networks failed over to an alternate path.  However, there was a problem with the LHCONE peering and it did not fail over correctly, so it caused transferring failure (over 15000 jobs in transferring status) and SQUID monitoring issues (both slate squid servers appear to be down in the CERN squid monitoring while they are actually running).  This has just been fixed (Sep 2 2021 around 10:35 AM Eastern time).
