In this case, due to such a rapid jump in fees, there was a big difference between fee estimates for different block confirmation targets, and different node implementations used different confirmation targets for the fees.

We have a workaround in place for Alby Hub as we run a blended fee estimator, so this particular force close issue will not happen again.

I don't believe it's a channel size issue, and Alby Hub users have full control over their channel management. You can open channels with whoever you want. If you decide to buy a channel with an LSP, then yes we help users there to make things simple to get started.

LDK is holding your own keys though. more like not your own channel management?

My LN channel on Alby Hub was force-closed

another case of "not your keys". chain fee spikes break channels between implementations as they cannot agree on commitment fees ((
