I bought a website a few days ago, its been reported as being held by the placeholder by both my and my friends comcast accounts (go to the site, its still "This page is coming soon!" kind of thing from godaddy), but at work, its updated to my hosting account, in fact i edited the page, put a real coming soon page, uploaded some stuff via ftp, etc. so why is comcast's DNS so slow, or is there something I can do to expedite the process?
