503 errors all of a sudden with agent http request

I’m suddenly getting a 503 error with message that the service is unavailable from an agent trying to reach this url:


The thing is, I can get to it in my browser and have tried several “is it down” type services which all reported everything is fine.

Since heartbleed is there some weirdness going on with http requests in agents?


Did someone flick a switch? Suddenly it’s all working again!

There shouldn’t be issues because of heartbleed - see this post.

503 Error Messages come from the server (in this case yours)… so I’m sure we can be much help here.
