Yeah,that was one of my first thoughts as well. I guess the raw.github example gets not only more traffic (irrelevant here) but probably also many more requests than hundreds of other sites combined.

Also no clue how actual RR DNS load balancing (without anycast) is still widely practiced, because I guess that also influences it a lot, you may be able to fix a DC going down on a completely different level than DNS. And my experience with cheap home routers is basically that they might cache hostnames for a month (we had stuff with tracking pixels in 2013-2017, EOLing some stuff was wild, we switched DNS and days and weeksl later still got valid requests to the old IPs).
