The anchors provide very basic services intended to help users who want
to use the anchors as measurement targets. They answer incoming ping,
DNS and HTTP(S) queries (see https://atlas.ripe.net/docs/anchors/). The
HTTP(S) service can respond with pages of various sizes which is
intended to help PMTUD tests for example.

It's possible that someone would want to check the TLS certificate of
the measured anchor, in which case a "proper" certificate may come handy.
