Prvni novinka: uz zase funguje peering mezi CESNETem a NetForce pres PASNET a router na 1.lekarske fakulte UK:

Do jake miry je tato trasa z hlediska CESNETu legalni a do jake miry je to chyba v routovacich tabulkach, k tomu by se mel vyjadrit nekdo z CESNETu.

K padu centralniho routeru CESNETU rab.cesnet.cz z minuleho ctvrtka - zatim se zda, ze problem je vyresen, rab nyni funguje, alespon z meho pohledu uzivatele CESNETu bez problemu.

Dalsi vec, kterou vas obstastnim, je zprava o tom, co predvadela nase pevna linka. Sice vede na CESNET, ale ten je v tom tentokrat nevinne, prsty v tom mel SPT Telecom, ktery problem na lince (ruseni) primo nevidanou rychlosti odstranil. Ty ping response time jsou skutecne a jsou nejvyssi, jake jsem kdy videl - 10 minut neni vyjimkou. Mozna by prenaseni packetu pomoci postovnich holubu dosahlo response time nizsich:
