Hertz - Hertz Web Site Down

I haven't been able to access the HZ web site all morning. At 4AM Eastern time I figured it was a maintenance thing, but still down. Have never seen this before. Message states:

We're Sorry.
The Hertz website is experiencing a system error at this time.
You may retry your request or we welcome you to contact us directly to complete your business.

Anyone have any idea of what the problem is?

It's not unheard of with them

Seems to be working now.
