Hello,

Anyone else having problems reaching Wikipedia?

I can't reach AS43821 (Wikimedia RIPE) from within the Portuguese NREN
(AS1930), via Cogent (AS174) -> Tele2 (AS1257):

Tele2's traceroute server (http://services.tele2net.at/traceroute.html)
reaches the same IP without problems:

Trying from $HOME_ISP, via AS6453 (Globe) -> AS1299 (Telia) works fine.

Looks like ge-2-5.br1-knams.wikimedia.org (130.244.6.250) is filtering you somehow.

Indeed, although I wouldn't know why.

The problem lasted the whole day yesterday, but it seems to be gone now.
I was given the tech contact for Wikimedia off-list; if anything rises
up again I'll get in touch with them.

Thank you for the reply, and also to everyone who replied off-list.

I should really look at NANOG more :wink:

All of our whois information is up to date, our peeringdb information
is up to date, and the usual generic email of noc@wikimedia.org also
works. We also have a few irc channels, bugzilla, and a technical
problem wiki page! If anyone has issues reaching AS43821 or AS14907 ,
please contact us directly if you want it fixed sooner than once a
week :slight_smile:

(Wikimedia Foundation - you can also contact me at lcarr@wikimedia.org
for any official business).

P.S. If anyone's curious, Tele2 was fine - there was an issue between
two other as's on a different return path. Hence the * * * after
hopping into our network post-border router.
