AT&T U-verse → Need a website tested from inside ATT network

I'm getting reports that one of the sites on our server is inaccessible from within ATT's network. Not sure if it's Uverse, DSL or something else.

Anyone willing to check a site for me?

PM me if you have a minute, I'd rather not post the site address here as this is a real request and not trying to spam a sites url.

Would appreciate a ping, traceroute in addition to a simple will it load in a browser test.

Thanks,

Sam
