Attempt #2, ~20 minutes later, IE: Loaded fine; queue position 4500+. About 40 minutes later when countdown gets to ~2800 that frame craps out on the next refresh inside IE. Blue letters "Page could not load" are visible. Refresh of the page does nothing.
Attempt #2 at reviving browser window #1, by reloading that sub-frame only from the context menu, puts me back in line at position 5000+. Countdown gets stuck multiple time for 20-30 minutes at the time, still going.
No tickets for me so far.
