So I've been having issues connecting. I'm only able to access the site by searching "hypnobooru down" on google and even then I get a "website unavailable" page that I reload at least once. From there it swings between showing the page I'm trying to access and coming up with yet another "website unavailable" page.

Suggestions?

Wait a while...

That's honestly the best suggestion I can give. The servers give out from time to time, and there's nothing we can do about it. The site usually doesn't stay down very long. I've gotten the "website unavailable" page several times over the past few days, but refreshing the page a few times always brings it back eventually.
