I actually contacted Network Solutions about this issue yesterday, and got the following response:
I am sorry for any issues you had. Our engineering team is aware of the issue, and is working on releasing a fix. As this is a global, system-wide issue, a repair may take longer than a “One-off” issue.
They didn’t give any timing or anything like that, so it wasn’t *much* of a response, but I know I always feel a little better when I know it’s not something wrong with my individual installation.
