Many things can cause lag and time-outs from a home connection, such as a really poor wireless signal or someone in the house uploading videos to YouTube and other sites like it. Downloading lots of stuff can also cause lag and time-outs in certain cases as well.
If you're still having connection issues, check to see if you're using wifi. If you're using wireless, try using wired internet as a test and see if that fixes it. If you can't try that, going into the same room as your router or trying on a computer that is wired could work as a way to test if it's the wireless connection as well. If it still has problems on every computer you tried or on both wired and wireless connections, it would be a good idea to see if you or someone else is downloading or uploading a lot of stuff.
If it was a problem with the server, or its connection, everyone would be experiencing the same issue and we'd have an official notice about any issues that were happening.
