First let me reference all my posts pointing to the same core issue.

In all my posts I've come to the conclusion loading entities is slow due to low download speeds, it goes extra slow when the connection stops receiving all-together, and then picks back up (perhaps error recovery but it takes a lonnnng time)

In game I see huge lag spikes before a disconnect, sometimes up to 2 minutes of no bandwidth moving at all, then I get a sudden spike of data like 34k/s for about 15 seconds where everything in the world catches up, text floods real fast etc etc. Then the game runs normal again at the 3 - 5k/s normal bandwidth. As soon as commands stop working, or typing doesn't register, I see my bandwidth meter drop to nothing, and sometimes this disconnects me to login screen.
The fact that this is intermittent, and doesn't effect everyone at once, generally means a hardware issue, or configuration issue on one of your many WAN IPs.


Now to strengthen my statements above, I ran an ICMP to my own ISPs gateway, with 0 packet loss, 100% packets sent and received which mean "I DID NOT LOSE INTERNET CONNECTION, to any server except yours"
I also ran into the following error messages several times while trying to post this, from your forums.

Service Temporarily Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.


I hope that's enough proof to at least start looking at networking/configuration issues, if anyone has some REAL input to back this up would be much appreciated =).
