This site is almost always quite fast for me. The server is in Portland and I'm in California, so it's not just me being close to the server (less chance of congestion, etc., causing slowness).
The times it is not fast are likely to be those when there is some cyber attack going on throughout the Internet, affecting sites much larger. Or when my ISP is having DNS issues.
DNS is the process by which your computer/browser converts a name like ripcitytwo.com into it's proper IP address. All connections are done by IP, not by name, at the lowest levels of the protocol. If it takes a long time to resolve the name to IP, your browsing experience can be impacted. This site, by nature, has elements served by 3rd party sites, like the tweets and images and so on. DNS issues would affect all those loading, too. No matter how fast your bandwidth it, DNS issues will make things slow.
Smooth and fast performance and 24/7 availability is my highest priority. Next is keeping the site free of spammers and spam.
