Error 521 Origin Down

[Dominik Peuscher]

Since last week I often get an HTTP 521 Origin Down when trying to get the version:

curl -I http://browscap.org/version

Is this a problem on my or on your side?

Hi Dominik,

We were performing some short bouts of maintenance and host migration - in theory CloudFlare should've cached the site so you wouldn't have noticed, but I've noticed that it's not caching as much as we previously thought. It should be reasonably stable by now though, so there may be another issue with CF connecting to our web head. It may be because the server is overloaded etc. or other issues, not entirely sure yet. I'm not an expert with these things, so going to have to ask a friend ;)

We'll investigate, but in the mean time, I recommend simply retrying until it becomes available.

Thanks

James

Thanks
