networking

Xe worries an incident report after a flapping IPv4 BGP session with their hosting provider affected the availability of some services over IPv4.

1. An important takeaway:

   The Uptime Kuma instance that caught this incident runs on an IPv4-only network. If it was dual stack, this would not have been caught as quickly.

My machine running status checks via Uptime Kuma is dual stack. This is something I need to look into as well.

TIL you can use an Apple TV as a tailscale exit node which according to the Mastodon thread also works when the app is running in the background. Cool use case. Being able to setup GitHub actions to use the tailscale exit node is a bonus.

Coincidentally, I also shared a post earlier today from Ruben Schade about his Apple TV.
