For many years, I would place my NameJet backorders right before the 11pm Eastern closing time. This was at the end of the evening for me, so the backorder time was pretty convenient as I was often shutting things down for the evening.
At some point in the last couple of weeks, I noticed a change at NameJet. The backorder closing time shifted one hour later – to midnight Eastern time. This gives people an extra hour to place backorders on domain names coming up for auction on NameJet and SnapNames. I believe this change is related to the integration of NameJet and SnapNames that is happening slowly.
