hello, I was attempting to SSH into an instance which was timing out. I also have a wireguard tunnel up, and ran a dig query for the internal hostname. The response started with stale records and had a bunch of duplicates, along with some cutoff answers:
$ dig AAAA fe-anchor-meta-anchordotdev.internal
; <<>> DiG 9.10.6 <<>> AAAA fe-anchor-meta-anchordotdev.internal

After a minute or so, it corrected itself:

This was right after I deployed the app, but more than 5 seconds (the TTL in the answers) had passed so I wouldn’t expect the stale records at the top to be in the answer.
