Network Solutions and associated WorldNic sites went down earlier today, jamming their phone lines and leading to questions and concerns from clients.
Network Solutions has Tweeted confirming that they are aware of the issue and are working to fix the problem as quickly as possible.
If your site is hosted on a Network Solutions or associated DNS server, it may be down right now. Rest assured, you aren't alone. With any luck, the sites will be back up and running without delay.
