ns-gce.sslip.io nameserver is retired
Previously ns-gce.sslip.io was a "half" nameserver: it didn't have a glue record like the three other nameservers, but the sslip.io nameservers included it in the list of nameservers when queried. ns-gce didn't do logging, also unlike its brethren. In many ways, ns-gce was the runt of the litter, and today we cull the herd (don't ask me for more metaphors; I'm stopping here).
Backstory
The ns-gce nameserver has always been problematic: I couldn't turn on logging because Google gouged me >$20/month for the logs alone (which was the impetus for the -quiet flag), so I made it "half" a nameserver: the registrar didn't have it as one of the three nameservers, but the nameservers themselves, when queried for the NS records, included it as a fourth.
But I want complete logs, so I'm fully retiring this nameserver.
Unfortunately, I signed up for a three-year GCP "committed use discount" which doesn't expire until 2026-11-02, which goes to show that a lot can happen in two years. Who knew that VMware would deprecate k8s in favor of Cloud Foundry? Who knew that I'd leave Broadcom for Majestic Labs in July 2024? Lesson learned: don't do 3-year committed use discounts.
