Is Left 4 Dead 2 down?

We query 161 of the most active Left 4 Dead 2 servers every ten minutes from our own network, and count how many reply. The baseline is the same servers over the last week, so this page compares Left 4 Dead 2 with its own normal rather than with another game.

What we measure is whether servers answer. If servers are up but you cannot log in, the problem is the login service, not the servers — that shows here as "normal" while the game is unplayable for you.
