OK it's back but that's not ideal.

Now I shall investigate how to self host, instead of relying on a CDN - how ironic

Yeah we’ve been frustrated with this as well. It’s a known issue between Cloudflare and Vercel, mostly on Vercel’s end. It’s an SSL handshake error that doesn’t complete, and both companies blame the other.

When we made Skypack we wanted to make sure that it was multi-cloud, to be resilient. But this is one of the side-effects of multi-cloud few talk about: platform disagreements 😅. Overall, though, the issue has been minimized but sorry to hear it’s still happening for customers (our monitors don’t check all regions yet so we only catch NA outages)

Of course I was preparing for doing a demo today!

The fallacies

The network is reliable;
Latency is zero;
Bandwidth is infinite;
The network is secure;
Topology doesn't change;
There is one administrator;
Transport cost is zero;
The network is homogeneous.
