RAL Tier1 Operations Report for 17th June 2019
| Review of Issues during the week 10th June 2019 to the 17th 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.
- upgraded xrootd on ceph-gw prod machines
