RAL Tier1 Operations Report for 20th May 2019
Review of Issues during the week 13th May 2019 to the 20th May 2019. |
- PPD had an unpatched Jenkins server which had been compromised. This identified on Friday 17th May. It was not a Grid resource (we believe it was an old MICE server).
- We are seeing high outbound packet loss over IPv6. Central networking intend to perform a firmware update on Wednesday(22/5/2019), morning.
- DUNE jobs are running again at Tier-1. This was reported 10 days ago but we believe had been a problem for longer.
- LHCb Castor (Disk) is now read only.

The file was replaced with a new copy at Vienna and transfer in debug stream is now green. |
