If your domain is hosted by roflhost.com then likely as not you'll have noticed it's been offline this afternoon.
This problem has been caused by issues with upstream provider justhost.com.
The problem came to light around lunchtime. I'd had a report from a client first thing this morning who couldn't access his email, which may have been the first signs of trouble or possibly just coincidence (it was fine when I checked).
Justhost tweeted ten minutes ago to say "We've made progress identifying the router causing problems. Approx half of servers should be accessible; we'll keep you posted."
Sadly, roflhost.com users appear to be in the wrong "approx half".
