ok getbig recently upgraded (a few yrs back) to a new server which ws supposed to be faster. which means getbig is right now running on the new server. HOWEVER you also have the old server sitting around collecting dust right ron?
soooo
why not run BOTH. Now you are thinking, that that will mean getting another public IP. NOPE....run both servers with getbig on them (same content) with ONE public IP for both internal ip addys. Your router connecting to the ISP (or the ISP itself depending on how u have it set up) can NAT to ONE address.
if u are not already doing this, its an option. If u r further interested pm me and i'll pm ya back with the nitty gritty or have your admin read up on NAT/PAT/Port Address Redirection
cheers
