Opazil sem namreč, da so odzivi DNS serverjev od OpenDNS postali porazno slabi. Prej je traceroute izgledal nekako takole:

Pobira resolver v Amsterdamu, čeprav so pred tedni instalirali enega v Frankfurtu, ki naj bi bil nam bližji.
Sedaj pa je zadeva taka:

Verjetno gre še vedno za Amsterdam, so pa poti precej neoptimalno zavite za moj občutek. Namesto ene solidne rute direkt do Frankfurta. Malo na levo, malo na desno - Budimpešta, Praga, Frankfurt, Paris... in potem ogromen latency na #8 - kaj sploh je SNGE za ena lokacija? Saint Germain ob Parizu mogoče?
