Testnet bootnodes might be outdated

[sonia-caraian]

I tried to deploy a node on b2 testnet following the documentation, and I got this error related to the bootnodes:

Bootstrap URL invalid enode=enode://8220fec60370080ba11940bd9b9e5352a8a1436fffe10593d40e21b8c7861ae71fad361cdcf2fadf1188661438556e203b4cf59ef1df91872871e0c6c4a5dfe6@b2-testnet-geth-p2p.altlayer.network:30303 err="lookup b2-testnet-geth-p2p.altlayer.network on 10.96.0.10:53: no such host

Are there any bootnodes I could use?

@Stonepapa would be possible to take a look? Thanks
