I've noticed lately that results are really slow after clicking on L1-3 D/O. It sometimes will take 3-5 seconds to show a result in the chat log. Tonight, it was taking like 10 seconds. I've never had connection issues before, but it could be me.
The server is running somewhat slowly tonight, but that doesn't appear to be related to the actual server at all. North American web traffic is extremely slow at the moment and getting slower (see www.internettrafficreport.com if you're interested in the specifics of it). I've not actually seen North America this slow in quite a while.
Now, I'm not experiencing slowness here to the extent that you are - I'm seeing one to three seconds a click, never ten - and that's while I'm also uploading an 11 GB file. Without getting into the specifics of Internet Gnomes and Packet Dragons too deeply, that just likely means that the route from you to the COTGonline server is worse off than the route from me to the server this evening.
I did do a purge of the GT database to ensure it was nothing on our end, and that didn't change the performance at all. This just looks like a connectivity issue, which appears to be locally quite bad for you.
