As of yesterday and after some 15 years I'm unable to access my email through webmail on the cox.com site. I get an "Oops, we can't find that page" notice.
Cox Webmail has been frequently very slow in the Santa Barbara - Goleta area. I've been almost always able to log-on, but Webmail interface has had lots of delay in responding. Replying to a received email occasionally doesn't work.
