cant sign into xbox live

SAME! I think the server is down. Wait a little while and try again.

Must be down I can't connect and my internet is fine.

I contacted My ISP and they are not having issues and I can connect and get everywhere.. else.. but like the above i also cant get in.. and the xbox live status is 'green'..  I'm wondering if there is an underlying problem with one of the recent updates from MS ...

yeah man i still cant get on xbox live and my internet is working fine wtf....

Having a problem here as well (Manitoba, Canada).  We have 2 Xbox machines and as of sometime in the last 18 hours (after 10 p.m. CDT, August 31) both stopped being able to connect to Xbox Live.  We have full internet - both according to our PC connections and according to the Xbox tests.

This is *NOT* an ISP issue - this is strictly limited to Xbox Live.

Same here in PA. Now I know what it feels like to be a psn user back in april :/

Yup, still down in southwest VA.  Getting MTU error.  Messed with router for an hour before seeing these forum posts.

Out in asheville, NC

Out in NB, Canada. Getting MTU error. I also messed with my router for at least an hour
