Are you guys still in business? I hope so... I love Hype.
Looks like the site is online. 
I did notice that the RSS Feed for the “Tumult Company Blog” was not working earlier today though. 
Yep, looks like they are back online. They were out quite awhile this afternoon. Glad they resolved the issue. I noticed something was amiss when I launched Hype and the intro screen was blank and I couldn't query for any updates. Thanks for the reply letting me know things were back up and running.
Considering no one at Tumult replied to you, maybe they're busy launching a new feature, kinda how Apple's website goes down just before a big project launch.
…or perhaps they're on vacation?
Some issues with our provider, apologies for the downtime!
