UAH has used the same instruments calibrated within the closest range, the same measurement technique, and adjustments have been physically grounded and were entirely expected as part of orbital drift and what have you.
USCRN is similarly high quality in its design, where ALL the sites use the same instruments, methods, and are sited well away from heat islands, however it's US-only and even younger than the UAH set going back only to 2005. Pic related.
Your second link about "major corrections" is to the RSS data set.
Moreover, the UAH and surface temperature measurements were very tightly linked up until 2006 or so, and my suspicion is that it's the surface datasets that have gone awry as they've also lost previous correlation with the USCRN.
