idk what a vtxo is and I couldnt see it on your landing page.

If it's similar to a UTXO, then I would think, in our scenario where your servers go kaput, then sure, I can unilaterally exit, but isn't the risk that these become unspendable on chain?

A vtxo is an off-chain utxo backed by funds that have been escrowed on-chain. There's always a series of presigned transactions that can take you from the on-chain transaction to getting your vtxo published on-chain (effectively turning it into a regular utxo). Your Bark wallet will make sure it has these presigned transactions before it registers any incoming payments so you'll never see funds that you won't be able to unilaterally exit from

Thanks for clarifying. There may still be a part I am missing.

Is this exit mechanism similar to a LN channel close, in the sense that funds get sent to a new address?

Yeah, the unilateral exit can be thought of as working in a somewhat similar way. Exiting can be done by spending the published vtxo to a new address
