When I run topologyUpdater.sh

it adds a bunch of relays in there.

My Question is should I have my other relay in there + my block?

I currently have my block and a bunch of other relays.

It’s up to u (it’s not a must)… for example I connected relays between them

If the BP will loss the connection with RelayA , RelayA will received the info from BP through RelayB
