Our site is doing fine and we have not had any net connection problems. The accesses do tend to drop on the weekends simply because fewer people are surfing those days. This congestion can make your access to art.net seem slow. It's something that we have no control over.
Sprint also seems to have alot of problems.
Also, if you pick providers that have a Mae-West connection, the access time will be extreamly fast if our provider peers with them. Hope this helps you in your search for faster access to art.net. I've been having a lot of trouble lately accessing and ftping to art.net.
