did a thing!
Big problem in #selfhosting is making sure you've set things up right: #dns resolution, #ports, rev/ #proxy. _Sometimes_ its helpful to query _from the outside_ of your local network.
`canuseeme` - a single binary #webservice that will query the URI you give it and see if its reachable by randos/services on the internet. A bit like a #webproxy, but can exercise it programmatically, and not limited to HTTP/S ports.
