07:20 AM PST: Web Hosting site access issues
Some Yahoo! Small Business customers may be unable to access their web sites at their domain names (web addresses) at this time. Web browsers may return a 404 or DNS error message when attempting to view these sites.
This will also affect our customers’ ability to access their sites using the alternate hosting URL, or accessing Yahoo! Site Solution or phpMyAdmin.
We are aware of this issue and are working to bring your sites back online as quickly as possible.
