I had a number of users who couldn't log in last night (from around 5:30pm to after 7:10pm GMT), as well as not being able to see lists of any tournaments at all (neither, running, pending or completed). These lists repeatedly disappeared and then later re-appeared. When our tournament started, the "Show Tables" list would not load and I couldn't see what was happening in the tournament (I also couldn't replace the half-table sit-outs with robots). I had to cancel the tournament.
