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.

Hello,

Anyone else having problems reaching Wikipedia?

I can't reach AS43821 (Wikimedia RIPE) from within the Portuguese NREN
