https://webtransport.day echo server down?

[achingbrain]

I'm not sure if this is the right place to open this issue, but there's no repo link on https://webtransport.day so I'm guessing here, my apologies if I've got it wrong.

The echo server at https://webtransport.day appears to be down because all connection attempts fail at the handshake step.

Could someone please give it a kick? I'm investigating a bug with WebTransport bidi streams and it'd be really useful to be able to share a simple repro using the echo server.
