Hey there, Frm the past few days, I am unable to access the site. I access the Internet via a 3G connection and my ISP has given me a shared IP address ( I am on a Mac.

Problem: when I try to open stackoverflow.com, it just keeps on connecting, and after some time it finally gives the error "The connection has timed out."

Temporary solution: I am using a proxy server to access the site, which is highly inconvenient, as my trial will expire in the next three days.

My firewall is off and I am on a Mac. I use internet tethering via an iPhone, and I am unable to access the site directly on my iPhone. The only temporary solution, for now, is the proxy server.

  • Since you said you use a shared IP, my first guess is that you're using the same IP as someone who has been banned. It's just a guess, though; I'm not a team member.

    if the case was about being banned, i guess the site would have atleast opened and displayed some message informing i am banned, i dont think it is the problem. Commented Dec 1, 2010 at 16:24
  • @Ibrahim For IP-based bans I don't think it does; based on this answer it looks like they just tell iptables drop all packets from that IP Commented Dec 1, 2010 at 16:28

    @Michael: More importantly, Ibrahim's IP falls into the block Jeff banned there.

  • @RBemrose :D Wow; I didn't even notice. You should post it as an answer Commented Dec 1, 2010 at 19:47

It appears that your IP is currently blocked on StackOverflow's routers/firewalls, as noted in A number of duplicates posted in the last hour by different users.

(Marked as Community Wiki, because Michael Mrozek linked to that post initially.)

  • Note: I assumed routers because iptables is a Linux command, and SO's web servers run IIS.

  • Good catch. That ban was ages ago, so they're probably willing to revoke it now (and you're probably right about the router/firewall part, they run Linux) Commented Dec 1, 2010 at 19:50
  • Why would the OP have been blocked only recently then?

    @Michael Myers: Because it's a shared IP... meaning that, from time to time, his IP changes.

  • Ah, yes, didn't catch that.
