Dear List Members,
I'd like your advice on my dns resolution problems for
edge-global.plcm.vc/A
When I can successfully resolve it is 1392byte / 84 A or a 1216bytes /
73 A Records answer.
But 50% of the requests get SERVFAILs or self referrals (testing from
AS8560).
Testing from outside AS 8560 with RIPE atlas (see
https://atlas.ripe.net/measurements/32509300) looks the same.
Using Quad1/8/9 I see these services needing sometimes >2000ms to
generate the answer.
Thanks
Thomas
