@enocom it’s basically a VPN tunnel by Cloudflare. It’s a Wireguard implementation from what I last read: https://developers.cloudflare.com/warp-client/warp-modes/#1111-with-warp

The Admin API team has found and fixed the issue and is seeing a drop in error rates. If someone who was affected here would like to confirm it’s working again, I’d appreciate it.

@enocom I confirm Cloudflare WARP fixes the issue for me too.

I’ve got on-call looking into this right now.
