Metric Value Notes
Chat rooms 9107 Includes all persistent rooms known (public/non-public and open/non-open)
Public rooms 8232 Only publicly listed rooms
Open rooms 6470 Only rooms which can be joined without password/invitation
Hidden rooms 0 Publicly listed MUCs where owners have requested de-listing from this directory
Total users 12752 Total number of users in all MUCs. Since we do not (and can not) track the real identities of users, this most certainly includes duplicates.
Domains 1975 Number of domains known; this includes non-MUC service domains and usually a single XMPP service has multiple domains (e.g. a base domain and a MUC service domain).
Stale domains 19 Number of domains which haven’t been reachable for more than 24 hours. Domains which are not reachable for more than seven days are removed from the database, unless they are being advertised by other domains.

Footnotes:

  1. So some people apparently find it useful to host "echo" services which simply reflect the query back to the sender. They act like a mirror. So when the search.jabber.network Crawler asks them for the software they’re running, it effectively asks itself without knowing that it does that. That’s what those "search.jabber.network Crawler" entries are.
