ETMX control was completely changed on Tuesday, no elog record

(Stefan Evan Kiwamu Nic)

We found the ETMX suspension was changed back to distributed control on Tuesday Nov 18, 2014 at 19:14. There was no elog documenting this. We expect this was an error (or maybe a BURT restore?). It's very surprising that we were still able to do ALS control at all in the interim.

The ETMs had been distributed for a long while, but were changed to offloaded while diagnosing ALS DIFF issues.

We've now changed it back to offloaded.

conlog reports only H1:SUS-ETMX_HIERSWITCH changed around this time on SUS ETMX, so no indication of a burt restore. Here is the conlog report of this channel from Tue morning until now
