Zcash Zebra nodes not appearing in Node Explorer

[mpguerra]

Hi,

We have a number of Zebra nodes running on Zcash mainnet at any given time and we're surprised that we haven't seen them show up in the zcash node explorer: https://blockchair.com/zcash/nodes

Is there anything that we need to do in order for them to be more visible/reachable?

Hey @mpguerra,

We checked our network crawler parameters, they are up to date. Also checked Zebra node's constraints and it should suit the crawler by default.

Crawler params:

magic_number = 24e92764
port = 8233
protocol_version = 170013

Could you please provide the list of IP addresses of your nodes?

Apologies for the delay in following up on this, at the time we didn't have any long lived instances for which we could confidently share IP addresses.

We've just noticed that the zecmate explorer (https://explorer.zecmate.com/network) does list 6 Zebra nodes:
