[pydotorg-www] Connectivity/network problems?

[Antoine Pitrou]

Hello,

It seems code.python.org (perhaps other hosts) sometimes has slight network
problems. Users have been reporting problems coding the hg mirrors recently, see
the latest messages on http://mercurial.selenic.com/bts/issue2595

(the machine itself looks fine, lots of free RAM and disk, idle CPUs; also the
Apache logs don't seem to show any mod_wsgi crashes or issues)

Even a normal static HTTP request can fail on the TCP layer (this is sporadic):

$ curl -v http://code.python.org/robots.txt
* About to connect() to code.python.org port 80 (#0)
*   Trying 82.94.164.162... Timeout
*   Trying 2001:888:2000:d::a2... Failed to connect to 2001:888:2000:d::a2: Le
réseau n'est pas accessible.
* Succès
* couldn't connect to host
* Closing connection #0
curl: (7) Failed to connect to 2001:888:2000:d::a2: Le réseau n'est pas
accessible.

(This is from a well-connected machine inside a datacenter. The IPv6 error
message means "network not reachable" but what's important is that the IPv4
attempt fails with a timeout)

Regards

Antoine.
