MAE EAST/WEST traffic

All of a sudden, http://www.mfsdatanet.com/MAE/east.aggr.overlay.html is showing very much increased traffic. The same goes for MAE WEST, on wednesday traffic was much higher. Anyone know what causes this? Did they fix some problem (the graphs have looked like something was saturated before (top of the curves seemed flat))? -- Mikael Abrahamsson email: swmike@swm.pp.se
