[Pdns-users] Slow downloads google drive

[Alex Trevisol]

Hello,

I'm not a DNS specialist this is a small dns resource that we have
implemented in the ISP, I really don't understand why with google drive
this problem happens, with google meet there is also a problem of slowness,
as the friend suggested activating edns and it worked but in fact it didn't
I understand exactly what this implies for google and the others in
activating or not, what I could verify is that google dns itself has this
option active. and also how would the edns work when it is a private ip on
the client side?
