Statistics on the Gemini space

This page presents some statistics on the current state of the Gemini space. It has been updated on 2021-06-01 00:04:01Z.

It cannot claim to represent the entire space. The real number of URIs is certainly higher. There are several reasons why many URIs are not in the database:

the capsule may forbid retrieval, through robots.txt,
we do not know all the URIs and some cannot be found from the ones we know,
Lupa has a maximum number of URIs per capsule, to save resources (currently 10000).

On this page, "working" means there was a successful connection recently. "recently" means "less than 31 days". "Dead" URLs and capsules are removed after 46 days and no longer appear in any statistics.

Currently, our database includes 315,882 URIs, 251,215 of them having been checked successfully (status code 20) and recently. Among the recently accessed, 179,731 URIs serve a Gemini content.

Certificates

TLS

81 % of the capsules use TLS 1.3, 19 % use TLS 1.2.

34.4 % of URLs do NOT send a proper TLS shutdown (application

close). Even 26.0 % of those who return status 20 are in that case.

A proposal to make this shutdown mandatory.

Ports

7 working capsules (0.7 %) use an alternative port

Addresses

748 IP addresses used. 13 % are IPv6.

TLDs

There are 160 TLDs in the capsule's names, and 776 registered domains.

By number of capsules

(There's a strong bias towards TLDs which have hosting services such as flounder.online, which has many capsules in subdomains. See before the TLDs per registered domains, which are probably more useful.)
