A term to build on. Strongest in momentum (D); standing is the one to work on (F).

How it is marked: each subject is out of 100 from the figures on this page (population is the 7-day average against the slots, standing is 100 less the top share, uptime the hours of the last 48 it was seen, performance its fps against 60, wipes the share of its wipes that kept half their crowd, momentum its rank against a week ago with 50 for no change). The grade is their average: 95 and over is an A+, 90 an A, 85 an A−, 80 a B+, 75 a B, 70 a B−, 65 a C+, 60 a C, 55 a C−, 45 a D, under 45 an F.

Server performance

This server has not answered a direct query in the last 48 hours.

48 hours: hourly readings. 30 to 90 days: one point a day, with the day's average and lowest fps, most entities and most memory. From asking the server directly; low fps and a climbing entity count mean lag.
