Whew. That was harder than it should have been.
It turns out that the half dozen sites I run on my WebHost4Life $9.95/month account were getting a little more traffic than I was really due for that level of service, so they encouraged me to upgrade. No biggie, I make a few bucks in ads here and there, so I can afford it.
Everything was going swimmingly until I accidentally fat-fingered the DNS entries for provost.org and peterprovost.org. Oops. Very bad.
Now, about 24 hours later, it seems to be mostly fixed.
I sure wish I could forcibly “expire” a DNS entry. Oh well. Live and learn. Thanks for your patience!
