I'm in Seattle which I think is close to the web host for CSBB. My latest download speed is about 29 mBS (fast) via Comcast. CSBB response is routinely fast, fast enough so I don't notice the speed. Right now it is in the wee hours on the East coast.
So, that probably leaves the rest of the path from my area to your eyeballs as suspect. I'd try some of the ideas already posted. I don't think the problem is at CSBB.
I just did a test searching for posts by the windbag, or was that gasbag? 1103 posts for Jon Eisberg in the past twenty years. Search results were returned in under 5 seconds. A fine collection!
