I learned my lesson when the data lines were cut, and the SETI servers were down for what seemed like a week. I had recently started running SETI, at the time wasn't able to get SETIQ to work through the firewall, and hadn't setup a queing proggy like SETIDRIVER.
The home herd all have SETIDRIVER running, holding at least 2 days worth of WUs, then we have a SETIQ running, that also has 3 or 4 days WU buffer. And if I am not mistaken, it is pointing to OK's proxy for even more buffer.
