Browsers displayed prominent error messages and warnings at about 9 a.m. PT when visiting

The HTTPS standard governs how Web browsers and Web servers set up encrypted communications, for example so that others can't eavesdrop on network activity to find out what you're searching for, but valid and up-to-date security certificates are required for such communications.

"An attacker on your network could be trying to get you to visit a fake (and potentially harmful) version of You should not proceed, especially if you have never seen this warning before for this site," Chrome warned.

Firefox said was using an invalid security certificate and cautioned, "Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified."

Microsoft said the problem stemmed from Akamai, which Microsoft used for the certificate service.

"We're working with Akamai on that. It should be fixed soon," said Microsoft spokesman William Zollicoffer.
