Due to occasional unavailability of this service (caused by me hammering BitTorrent and maxing-out my bandwidth) I have done what I should have done ages ago, and moved phpArcScan to a better hosting service. So it's off my cranky Linux box, and on to dedicated hardware and decent connection. Hopefully this should provide a better service for everyone!
The new service can be found at:
