	As of the 8th of August there was a big reduction in the
	number of TLD zones which filtered queries with unknown
	EDNS version or unknown EDNS flags.

	While there is still work to do to improve EDNS compliance
	this is a big step forward.  Thank you.


	As some of the operators involved also serve part of the
	Alexa top 1000, a visible step improvement has been seen
	there as well.
