Summary

After Pectra merged at epoch 115,968 an invalid block was propagated and accepted by execution clients. The network forked between Erigon / Reth working correctly and Geth / Nethermind / Besu which did not have the correct deposit contract address.

The execution bug has been fixed but because so much of the network was affected, the consensus layer is struggling to build a stable chain. If you run a Holesky validator, please begin trying to resync it. Do NOT disable the slashing db. Slashings are causing more instability at this moment.
