When browsing the web, I occasionally get redirected to "/cgi-bin/redirect.ha". Closing the browser or flushing the cache seems to fix it sometimes, but not always. Sometimes I'll see from Google:
Error 404. That’s an error. The requested URL /cgi-bin/redirect.ha was not found on this server. That’s all we know.
AT&T support was useless on fixing this issue.

This is a known bug in the Motorola NVG510 modem supplied by AT&T U-Verse. It has nothing to do with your computer or browser, and it's not a virus or abuse attack:
Basically, when the NVG510 looses connection, rather than giving you an error message it redirects all traffic to "/cgi-bin/redirect.ha". Thus visiting to "www.example.com/whatiwant/" returns a redirect to "/cgi-bin/redirect.ha". The browser is free to cache such data, and may do exactly that. Thus you sort of randomly ended up with "redirect.ha" even after your modem retains connection.

2I'm also seeing this with AT&T Gigapower with NVG599 modem. Except i'm seeing
/cgi-bin/ipdiags.ha. – Adam Johns – 2015-10-03T21:13:30.227According to https://www.quora.com/How-can-I-get-rid-of-AT-Ts-redirect-error-page a couple of the issues are that (1) the modem/router returns a 301 redirect, which your browser caches, and (2) AT&T has some kind of nonstandard DNS setup. Apparently changing your DNS settings can help.
