RAL Tier1 Operations Report for 13th December 2017
Plans for the Christmas and New Year Holidays
|
- RAL is closed after Friday afternoon 22nd December and will re-open on Tuesday morning 2nd January. Plans for the holiday period follow the pattern established over recent years and we will try and respond to urgent service-affecting events. The Tier1 on-call team will be in place throughout the holiday and will respond to alerts as usual. They will also carry out some additional checks throughout this period. The Machine Room and network operations teams will also be providing on-call cover during the holiday. However, please note that support will be limited on Christmas Day, Boxing Day and New Year’s Day.
Review of Issues during the week 13th to 20th December 2017.

Echo:
• Background scrubbing has been going on. This has flushed out more bad disks – causing some callouts through the week.
Network:
• Emergency card replacement at Harwell PoP on Thursday morning. This was announced to us and caused a short break in two out of the three OPN links (as expected)
Infrastructure:
• There was a successful generator load test last Wednesday (13th Dec).
Certificates:
• The re-updating to pick up the updated UK CA certificate in the IGTF 1.88 rollout took place successfully last Tuesday (12th) as planned.
