sitemeter interrupted?

I just wondered if anyone else has the same problem.  I can't access sitemeter this morning at all.   The message says the following when I key

The connection to was interrupted.
I use the site to see how people are coming into the blog, what they are searching for.  It can be very useful sometimes to get a trending story up and running.  Have they cut me off?   Or is it a general problem?

UPDATE - back on.  I emailed them and within 30 minutes, it came to life.

UPDATE - no It's gone again.
