RAL Tier1 Operations Report for 28th January 2019
| Review of Issues during the week 21st January 2019 to the 28th January 2019. |
- Embarrassingly it's still business as usual at Tier-1.
- Last weeks ARC-CE issues are steadily being resolved. This includes the creation of a new ARC-CE that is hoped to be in production by the end of this week.
- We did experience a network issue over the weekend that impacted cvmfs. As such as we took a hit on batch farm CPU efficiencies. The issue was resolved but as the efficiencies are calculated on the completion of jobs it will take a couple of days for the efficiencies to be back up to normal.
