DoS = Denial of Service.

I've been offline for the last couple of days - couldn't access this site.  Apparently, they blocked some IP ranges to try and stop the DDoS attack, but I got blocked.  The main issue I'm worried about is how many other people have been blocked...  Currently accessing this from a public computer and it seems okay...

Oddly, computer at work got blocked too, but it's IP is quite different from my home IP.  They said they'll whitelist my IP, but then, I'm mainly worried about other legit users trying to access the website...
