Broke lock @ 08:41 :( Not bad for a maintenance day!

It seems as though after dropping lock the IFO came back twice (on its own or with some help from Ed?), with one locking attempt that failed in locking DRMI_1F.  

The attached plots show the guardian state from 13:20 UTC to 16:20, the longest steps in the relocking process are still finding IR and locking DRMI, the long DRMI lock was about 8 minutes, the total time to recover from the lock loss was about 40 minutes (inlcuding the failed attempt), and the second time it took 15 minutes.  

I think we can say that we now have some "one click" locks, unless Ed had to intervene in some way to lock this.
