Hi all,

I'm having a surprising issue, whereby Emacs -Q sometimes doesn't seem to be able to reach dx.doi.org; other websites work fine, but for that particular one the network process stays in "connect" state for a while, then goes to "failed" state. I'm pretty sure it worked a few days ago, and it has worked intermittently today. I'm on the latest pretest.

Before opening a bug report, I'd like to make sure that I'm not doing anything silly: I'm trying to open http://dx.doi.org/10.1016/s0262-4079(08)62292-7 ; with eww, I get "Loading http://dx.doi.org/10.1016/s0262-4079(08)62292-7...". With 

  (url-retrieve
   "http://dx.doi.org/10.1016/s0262-4079(08)62292-7"
   (lambda (&rest args) (message "args: %S" args)))

I get 'Contacting host: dx.doi.org:80', and nothing. After a few calls list-processes shows this:

dx.doi.org      failed   *http dx.do... --           (network connection to dx.doi.org)
dx.doi.org<1>   failed   *http dx.do... --           (network connection to dx.doi.org)
dx.doi.org<2>   connect  *http dx.do... --           (network connection to dx.doi.org)

Setting url-debug doesn't seem to make any difference.

Using curl to get the same page works fine. I tried to have a look in wireshark, but it seems that Emacs never opens a connection; at least, I can't see anything.

Does this ring a bell for anyone? Can anyone reproduce it? I can't always reproduce it myself; it happens for a while, then it goes away. In all cases the website is still reachable with curl.

Clément.
