Did anyone else have trouble with their Linode on Host3 today? At 3pm (EST), my Linode quit responding. After checking, I found that it had been shut down completely. It took me 20 minutes and 3 attempts (using the queue) to get the thing to powered back on. I can see nothing that would have forced the machine to shut itself down, nor did I find any errors in the logs. This is the first time I've seen something like this happen.
