All FTH sites seem to be down

Any idea why this keeps happening?

This is the second time this month that FTH has been down. This is what I get when pinging the IP address:

Pinging toastmastersclubs.org [50.19.253.65] with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.

I've even tried 3 different browsers to see if that was the problem.  

The worst part is that when it's down, it's often down for a decent amount of time.

It might be sort of up now- I got a DATA TRANSFER ERROR with a pop-up that said to notify the support team:
  

Yes, a previous outage lasted several hours.
This is the 3rd time it went down within the last month
What is going on?
