If it's a big crash on Roll20's end, it shows up on this Status site link: <a href="http://status.roll20.net/" rel="nofollow">http://status.roll20.net/</a> and yes it did record errors today (June 25) in the Quantum Roller (that's the dice), and in Shard 45 (that's a server-area that matters for only a small portion of games on Roll20).
