What we have measured about this server
What we have measured
US Coop-20 Fire-Fly had 11 of its 20 slots in use when we last checked, which puts it well over half full. We have readings for 21 of the last 24 hours, and across them it averaged 8 players against a peak of 16 — a swing wide enough that the hour you arrive matters more than the average does. It reported 20 slots over those same checks, so it typically runs about 40% full. Over 8 days of checks the fullest hour has been 14:00 UTC, averaging 10 players. It ran 41 different maps across 154 checks, changing map at least 129 times — most often c1m1_hotel, which came up in 14.9% of them. It has answered 100% of our checks over the last 7 days, which is as steady as this list gets. It has been on JoinGG since September 2026, about 2 months, without a vote so far.
