Location changes do not involve additional cost unless the new location is more expensive than the old one. You can change the location through our Order page at https://www.nfoservers.com/order.php
, by selecting the new specifications for the server to include its new location and then using the "This is a change to an existing server" option at the bottom.
If you'd like, we can also take a look at the routing to and from these clients to see if it can be improved. Please send their traceroutes to the server and IP addresses, or at minimum just the IP addresses, to email@example.com
