Operational issues:

• LHCb job pressure was unstable throughout the week
  • Lack of MC productions, lack of jobs as a result
  • There is some improvement since yesterday
• Echo transfer issues last Monday
  • Problems with macaroon rejection after xrootd sitename change
  • Small impact on LHCb transfers, fixed within an hour since discovery
• IPv4 routing issues from LHCb ETF machines to 23 ECHO gateways (GGUS:1000451)
  • It is impossible to establish a connection to those gateways via IPv4 from `etf-0[56].cern.ch` machines
    • on connection establishment ACK packet does not reach the gateways
    • Seems to be routing issue, which is now tracked in JIRA (INFRA-483)
    • To mitigate the problem, affected gateways were removed from production
• A few spikes of failed WGProduction jobs last week
  • The usual issue -- buggy xrootd client
