Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

For a couple of days now, I have not been able to access Stack Overflow via my WiFi (though can through 3G, which is how I'm connected now).

It always just returns "Could not connect" no matter what browser or what device, and a traceroute did 30 hops and "Request timed out" for all of them : (

I haven't spammed, and although my reputation is low, I don't think I've had any negative responses. I'm just more of a reader than an active user, as I can solve most of my problems from reading other threads. Regardless, it seems the Stack Exchange network has blocked my IP. Is there a way of getting this reversed? : (

I'm 75% designer / 25% developer, so need SO frequently!!

Hope someone can help.

Can you ping or tracerout to using your wifi? – Oded Feb 27 '13 at 21:22
Traceroute timed out on 30 hops… (I assume that means no?) – Chris Fox Feb 27 '13 at 21:23
What IP are you getting on pings? – Oded Feb 27 '13 at 21:24… : s – Chris Fox Feb 27 '13 at 21:26
Well, that's the correct IP. Are you getting results from it? And at what point does the tracerout stop returning stuff (that is, what is the last address that it shows)? – Oded Feb 27 '13 at 21:28
I'm not sure I'm doing it right; I'm on Windows for a start, so not sure I should call it Traceroute. I did a tracert in Command Prompt. It – Chris Fox Feb 27 '13 at 21:32
…just attempted to connect to thirty times, and said "Request timed out" each time. – Chris Fox Feb 27 '13 at 21:33
.12 or .16? ........ – Pëkka Feb 27 '13 at 21:34
Oh, sorry. Last one was a typo. – Chris Fox Feb 27 '13 at 21:35
If you are on a windows box, try ipcofig /flushdns in the command line – Oded Feb 27 '13 at 21:37
It has "Successfully flushed the DNS Resolver Cache", but I still can't access the site(s) and tracert is still just timing out… :' ( – Chris Fox Feb 27 '13 at 21:41
Have you reset your wifi AP and your router? – Oded Feb 27 '13 at 21:45
Yep. The old 'turn it off, run it back on again' was the first thing I tried! : p. Thank you for your help. As I say I'm more designer than developer, so these more technical issues stump me immediately. – Chris Fox Feb 27 '13 at 21:48
Do other sites fail? Sister sites, like e.g. Can you connect to other web sites? Any funky firewall configuration on the machine or the WiFi router? – vonbrand Feb 27 '13 at 21:52
Are you with Virgin Media by any chance? Can't access any Stack Exchange site – Pëkka Feb 28 '13 at 9:58
