Need to test jgc.org as part of CloudFlare Railgun testing

Just siphoning a little HN traffic. Thanks.

EDIT: I didn't expect this to get any up votes :-) Thanks, fellow HNers.

EDIT: Thanks. Railgun worked but my web host didn't like the sudden surge of traffic and shut off (now need to chat to my web host). The test meant the normal CloudFlare acceleration was turned off and all traffic was sent through a single IP address. Turns out my web host didn't like that :-)

EDIT: Now that that's over, if you feel like it you can read about CloudFlare's DoS statistics: http://blog.cloudflare.com/the-wednesday-witching-hour-cloud...

You know how I can tell who's using CloudFlare? Every time I visit their site I'm informed my computer is part of a botnet by a page that has all the credibility of one of those "your computer has an IP" popups. :(

I absolutely love cloud flare and I think they have revolutionised the way I deploy things to the Internet. Yet the fact that I can not turn off their security completely means that I have plenty of users complain about being blocked.

It took about 1 minute to load.

Then I got this:

This page (http://www.jgc.org/) is currently offline. However, because the site uses CloudFlare's Always Online™ technology you can continue to surf a snapshot of the site. We will keep checking in the background and, as soon as the site comes back, you will automatically be served the live version.

Thanks. That's just what I was looking for. As with all real tests that thing you least expect happens: I managed to cause DoS detection to activate on the origin server and it took itself offline. Now to chat with the hosting provider...

Same thing, except it tells me, "No cached version is available."

Worked a couple minutes ago, though.

Getting the 'retry for a live version' banner.

Also, one of my clients had to turn off Cloudflare this week because of customer complaints. They weren't using Railgun, but were getting too many false errors with HTTPS enabled (https -> cloudflare -> https server). They thought it might be an odd interaction with SPDY.

Yes. Railgun worked fine, but I managed to kill my origin server by accident :-)

Did you talk to someone in support about the HTTPS thing?

Just got off the phone with my client: They had an email exchange last week that was inconclusive. Then filed a support ticket this week when they had to turn Cloudflare off (business plan) and didn't hear anything back. I just had them re-file the ticket since it looks like Cloudflare had some support ticket issues.

I'm a fan of Cloudflare and would love to have my client running again. Do you guys have a network hacker on staff we could connect them directly with to get to the bottom of things?

Hi, I'm on the CloudFlare support team. Which domain was this in regards to? I'd like to look into this further. By "false errors" do you by chance mean SSL mismatch warnings?

Hi, users were getting "Error 102 (net::ERR_CONNECTION_REFUSED): The server refused the connection." on https pages. See original ticket #5880 and new ticket #6001.

If that doesn't come up my email is in my profile. Happy to connect you directly with their CTO.

[edit: added new ticket #]

Did this happen yesterday? Did the client happen to be in Tokyo? We had a temporary issue in our Tokyo data center (related to our rollout of SPDY) that would have caused the symptoms you describe. It's fixed now and there's a check in place to confirm that SSL is answering properly before a server starts receiving traffic.

Sorry for the problem! Thanks for reporting it.

Sadly no Tokyo customers. Any similar US issues? They had problems last Fri through this Monday with U.S. customers before shutting Cloudflare off.

Hmm... will look into it more. Thought it was an easy explanation since we had that issue yesterday in Tokyo.

Took 45-50 seconds to load and finally go this page http://imgur.com/kSJRv.

Hope that helps.

London 22:53h took 50s to respond with an error page:

  This website is offline

  No cached version is available

Let me know how it goes. We're exploring CloudFlare now and think Railgun has massive potential for our uses.

Look at using http://blitz.io for load testing.
