Network Solutions, one of the major DNS Registrars, is having trouble with their DNS servers, which is affecting some of our clients.

Your site may be affected if you are using Network Solutions as both your DNS Registrar AND to host the DNS for your site (ie, your domain uses worldnic.com addresses for its nameservers).

From their site (as of 9:55am):
"We are currently experiencing a widespread DNS related outage. If you are attempting to contact us to report a product that is not working, please know that we are aware of the issue, and are doing everything we can to resolve all issues as quickly as possible."

If you are affected by this issue, please keep an eye on Network Solutions' website for updates:
