I'm not sure what the resolution to this is. Maybe someone else has experienced this. We are monitoring some HTTPS sites, three to be precise, which are hosted behind a Content Delivery Network. The first monitor is looking at the parent URL and the other two monitors are looking at child sites. Several times a day, the sites will return a HTTP 400 Bad request status. They don't all return a 400 error at the same time. it will move from one site to the next in succession. I can hit the sites fine with a browser while Orion is showing them 'down'. A 400 error is typically client side. Any idea what's going on here?
