- 13-May updated dcache 9.2.27 -> 10.2.12
  Declared at-risk (intermittent) outage
  Smooth update
  It seems only up to 7 jobs may have failed on direct access (pilot error 1361)
  Part of motivation was to enable firefly monitoring.
  Success though content not as expected
  (expected latest changes didn't make it in this release?).

- switching WNs to OSG24 (at UM)
  noticed some were not running boinc jobs; fixed scripts.

- EL9 at MSU: continuing to investigate node record corruption.
  Will likely ask for satellite software update (in next couple days).

- 10-May Saturday generator test at MSU data center = qualified success
  smoother than expected (i.e. no temperature fluctuation)
    when dropping A-side (on UPS) or B-side power feed
    The control system maintained (UPS) or restored full power in the racks in fraction of a second
    when dropping both, first from UPS, then 2.5 MW generator within a minute
    with very minimal temperature fluctuation for all steps
  –> all the normally unattended steps were a full success
  last step: going off the generator was somehow difficult to engage
    then all AC units failed to restart automatically 
      and took time and effort to coax back on
    all C6420s and most R6525s shut off on temperature alarm
