I get issues like that every so often. It may be a problem in the Internet Core routers, maybe a bad route or dead route. Could be a bad DNS cache on your ISP's DNS or on your client computer. Funny thing is, when you learn about the internet, you begin to realize that with all the seperate systems that have to function properly, it's a wonder we ever get to where we want to! LOL!
Sorry...i know that probably didn't help!
