Maintenance for the week of March 25:
• [COMPLETE] ESO Store and Account System for maintenance – March 28, 9:00AM EDT (13:00 UTC) - 12:00PM EDT (16:00 UTC)
Mine are linked (have checked). The drops aren't on anyomore apparently, weren't since yesterday . Watching Bethesda at home right now - there's nothing.
According to a pattern they enable drops every second weekend starting from 17pm Friday till the early hours of Monday, so you can earn up to three crates, one for each day. This time, though, they enabled them at 17pm on Thursday because of the pvp event.
I agree; past experience shows that drops usually start on a Friday, and don't usually last past Sunday. They might start earlier than Friday for an event or other special occasion-- such as the launch of a DLC or chapter, or a special episode of Bethesda Live-- but I don't remember them ever extending past Sunday.
And whereas drops are normally posted at about 10 AM ET of the morning after they were earned, it seems that drops earned on Sunday get posted at about 12 AM ET. I think the hours when drops are active might end during Sunday evening, so if you watched on Sunday but it was too late in the evening, you probably won't get a drop for Sunday.
