there are 6 geographically distributed legacy monitors that have been running for 14 months. They run nostr.watch and effectively populate the data for the nostr.watch API that is used by many clients (habla, nostrrr though now NIP-66, snort for almost a year, + many more). that data is from the new monitors that started to be deployed during SEC-01 and reached full-scale a few weeks ago.

I forgot to mention nostr.watch API is also sort of the backend for blastr, sorry everyone, blame @Deleted Account
