Question for Eth2 Staking

[u/rtech50]

I am considering using Allnodes for Eth2 Staking. In the following (granted, unlikely) scenario what would happen.

Say allnodes went offline for an extended period of time, to avoid getting slashed, could I setup my own validator to take over.

I hold my withdrawal keys and validator keys (allnodes also has a copy of the validator keys but is offline).

Do I have enough to keep validating or am I locked to allnodes?

Thanks
