SAM test issues:

1. Timeout failures on svc20 (AAA server) on Friday - Jyothish removed from cluster. Telegraf and Icinga were also down. Jyothish has ticket with Fabric.
2. Network problems on Saturday
3. After 2. the other AAA servers and manager failed 'federation' test fairly consistently since. Restarts of the usual services by Katy and Jyothish has not fixed it.
4. ARC-CE xrootd-access test requires AAA. This has failed intermittently due to 3. Fortunately not every CE is failing the test simultaneously, so we do not get a red mark in the summary. 
5. New tokens tests for CEs are generally working, but the 'basic' test is in warning due to jobs almost entirely landing on 2018/9 WNs which do not have IPv6 (Tom Birkett might comment).
6. 'Connection' test for Antares endpoints in warning due to no IPv6 - how are the tests for the new EOS nodes going?

Job efficiency dropped sharply during the network issue on Saturday. 

Suspect CMS running empty pilots again - there are major monitoring discrepancies I am seeing (Tuesday night). Have messaged Submission Infrastructure team.
