RAL Tier1 Operations Report for 3rd June 2019

Review of Issues during the week 27th May 2019 to the 3rd June 2019.
  • Ongoing, we are seeing high outbound packet loss over IPv6. Central networking performed a firmware update to the border routers but this didn’t resolve the issue. Plan to move connections to the new border routers in Mid June. Will do this before trying to debug any further.
  • The old LHCb Castor instance lost three disk servers over the weekend!! We don’t intend to spend much effort recovering them. The old LHCb castor instance will be decommissioned (no files will be recoverable) on Friday 7th June.
