@tie @dangoodin Quite so. The flip side of all the redundancy, roll-over strategies, local root instances and global DNS services such as 8.8.8.8 is that diagnosing inconsistencies is devilishly difficult and impossible from a single vantage point on the internet when anycast comes into play. The temporal effect is also a huge complication. What we saw five minutes ago may be completely different to what we see now. Not sure anyone has good answers to this beyond wide-spread monitoring.
