Review of Issues during the week 10th June 2019 to the 17th June 2019.
  • Scheduled optical replacement work on the Janet Core in London suggested that there could bea prolonged outage at RAL. 
 ** Additionally there was concern that IPv6 may break and notfailover correctly (based on previous experience).  

 ** In the event, the outage was momentary andno services were impacted.   Both IPv6 and IPv4 failovers worked correctly.
  • CMS CPU efficiencies are currently describing a veritable sine curve over a weekly period. 
 ** Investigations seems to suggest a 100% failure of “log collection” jobs at RAL. 

 ** However, despite extensive investigation on the part of the Tier-1 Liaison no one seems to know what this job typedoes (other than the obvious), and who is actually responsible for the monitoring/processing ofthis job type as CMS
