|The Muon1 statistics aren't updating this weekend because they're turning the power and the network on and off in the building where the stats server is. Naturally, the server can't do much without power or network. The repair men will probably have finished their work by Monday, at which point updates should resume, or maybe it will take the rest of this year.|
|...and they're back. With no intervention from me whatsoever, actually.|
Looking at the graphs it seems that the power was on for nearly all the time (because stats were being generated with no new results), it was just the network that was out.
