SAM tests on the AAA proxies and manager are no longer failing. AAA was quiet over the weekend so all SAM tests were green.

AAA became more busy since yesterday, and interestingly the maximum cap, which previously always appeared to be ~1GB/s is now going to ~1.5GB/s. This may be a result of my change to the throttling last week, which I increased from 200 to 400 concurrent connections on ceph-gw10 only. Puzzlingly, both gw10 and gw11 seem to have increased their max rate equally. I would like to play further with this setting, although I do have 2 observations (perhaps related to each other) on making such changes: 1. They don't seem to come into use for some days after making the change. 2. I am not sure if there is some particular order I should be restarting services on the various redirectors. 

Anyway, some of the WN tests are failing intermittently, and yesterday these were enough (10% or more) to make the whole day fail site readiness. It's not just the WN-xrootd-access test failing, although this is one. Also seeing a couple of failures on WN-analysis and CONDOR-jobSubmit.
