If Website Worth Up or Down says a site is up but it still won't open for you, the issue is usually on your end rather than the site's — start with these:
ipconfig /flushdns).If none of that helps and the site shows as “down” above, it's most likely an outage on their end — try again in a few minutes.
When you load this page, Website Worth Up or Down makes a live connection to comcast.com and records exactly how it responds — the same request your own browser would make. Alongside the basic up/down result, we run a handful of supporting checks: DNS resolution, SSL certificate validity and expiry, domain registration status, and which ports respond, all shown in the cards above.
