Error Response Codes When Bubble is Down

Bit of a random one - I’m working with a client who loves how quickly we’re building with Bubble, but is a little hesitant to (i) pay the full dedicated hosting price or (ii) face any meaningful downtime if the system goes down.

They’re proposing to ping the page to check for an error code before directing users the the site and are asking what HTTP response code is sent out when Bubble comes fully down (e.g., 400, 404, 500, 503, 504, etc). I’m guessing this is largely dependent on what’s going on with the platform when it goes down, but any information anyone has (or even screenshots from when the platform has been down recently) would be super helpful. I’d love to get them across the line on this, but this is well outside the scope of my expertise.
