Here in the Indy metro area, our 3800HGV-B gateway has been updated.  I am guessing that it occurred around 4:30AM on Tuesday, March 20th.  Only reason I say that is that there was a DSL retrain event at that time, as well as an outage of about 2 minutes (according to the gateway's stats).  Interesting that it didn't trigger a restart of the gateway.  

Everything seems to be fine -- no loss of configuration settings or other anomalies noticed.
