Allow me to clarify a couple of things….
We had a temporary system outage today due to a system upgrade, which may explain why you were getting offline (timed out) instead of the usual HTTP 502.
Unlike all the other trackers that seem to work properly all the time, we have a significantly higher network load and as such, sometimes at our peak hours, the tracker has a hard time keeping up due to how overloaded it can get at times. This is the down site to being the world's largest free online video bank.
