I have the feeling that everyone had problems connecting to games this past weekend. If you were wondering what is going on (in Xbox anyway), here is a link to the status page for Xbox Live Status under Microsoft's support pages for Xbox Live. Go here if you are banging your head against the wall endlessly rebooting your Xbox or router; the issues might be more widespread than your own network connection. EDIT: Okay this is an old tip for some people, but for newer Xbox gamers hope this helps.
