Site appears to be down

Hello! Our site isn't working for our visitors. I get the following error message and it won't load:

The www.johnhaypartners.org page isn’t working
www.johnhaypartners.org redirected you too many times.
Try clearing your cookies.
ERR_TOO_MANY_REDIRECTS

I can still make edits to the page, but they won't publish. Does anyone have an idea how to fix this? We have a campaign starting tomorrow morning and it will be a mess if this site isn't up.

Thanks!
