Hello Jim,

While not an extensive analysis, I managed to gather some results last
night. I performed 15893 root zone AXFRs from K-root from 245 RIPE Atlas
anchors (distributed all over the world) for a period of about 210
minutes. Not a single AXFR failed.

The fastest AXFR took 3.3s, while the slowest took 62.5s.
