Ticket replied to, merged this with main 500servers support thread.
The actual maintainence work has not yet been fully completed Although even so you should not be experiencing any worse connections.
If you can do a tracert (START >>> RUN >>> CMD >>>> and type "tracert 500servers.com" to one of our servers that might help to identify if there is a problem with routing to your region or if there is a specific issue on this end.
