Wikimedia sites not reachable through CenturyLink ISP
Closed, ResolvedPublic

Description

I am using the Century Link ISP from Saint Paul, MN. No Wikimedia sites can be reached, other sites work fine.

Reports on http://www.isitdownrightnow.com/wikipedia.org.html indicate that this affects other CenturyLink customers and has been going on for 45 hours.

Two tracert ouputs, taken 30 minutes apart:

Please provide your IP for a reverse traceroute — you can omit the last number for privacy reasons if you want.

Also, it'd be helpful to know if the site is completely unreachable or just very slow to load. From the traceroute it looks the latter but I'd like to confirm.

I tried ping/traceroute from CenturyLink's Minneapolis PoP using their looking glass. It looks normal so far:

@AxelBoldt could you verify if this is still a problem for you?

I also created a RIPE Atlas measurement from 24 probes that are in CenturyLink's network (AS209).

That's measurement 2407575 and I see nothing abnormal in it so far.

It is now 4:18 PM CDT and I can reach all Mediawiki sites again.

OK. It's impossible to find out what happened without more data unfortunately :(

I'm going to resolve this for now but feel free to reopen (or open a new task) if something like this happens again. Thanks for the report.
