Individual Cloudflare server nodes pull traffic independently


I feel comfortable assuming this is the case, as any other architecture just doesn't make sense.

Quote:
Certain nodes aren't whitelisted well enough and occasionally pull enough request from the actual WP servers that a security module on those WP servers (intended to handle DoS attacks or the like) puts them in a sin bin for a while


I don't believe there is any such service on the server, but I'll double-check at some point today.

Quote:
Restarting one's browser or clearing certain cookies might make Cloudflare forget which server node a user has been allocated to, hence why restarting a browser makes the problem go away - after the restart the user is sent to a non-sin binned server node (this might also explain why some users have found they had to restart twice on some occasions - as they were conceiveably unlucky enough to be reallocated to the same server after the 1st restart)


This seems unlikely, as I believe the cloudflare service is allocated to users by way of anycast DNS (which then may or may not hit a load balancer). Simply restarting the browser wouldn't clear the DNS cache local on the machine, much less the ISPs cache on the recursive DNS server.

Quote:
Despite the fact that I'm sure the servers are likely all whitelisted, etc. I think there's a certain "elegance" to this theory - such that I thought it worth sharing


Good theory, just don't think it pans out.

I had a Cloudflare issue today. When I went to WP I got a page that said my computer had a virus and I was blocked from the site. But it allowed me to enter the text from one of those nearly impossible to read graphics to prove I was a human and not a bot. I ran a disk scan with Eset for the Mac and no viruses were found. Now this evening the problem is gone. I'll take a screen shot if it returns.

That's intended functionality.

It's intended to block clean computers? That doesn't make any sense.

It's intended to block suspicious activity. That doesn't always mean your computer has a virus.

It's intended to challenge after picking up possibly suspicious activity. That doesn't always mean your computer has a virus or that there is actually anything wrong at all[?]

^FTFY (changes in red).

I've had this message once and was using an uncompromised Ubuntu Linux desktop at the time (on a connection with a static IP and the few machines on the LAN all being mine), I don't know what heuristics were tripped to 'spook' Cloudflare (I was browsing normally) but I didn't think completing the captcha was unreasonable (I would probably mind only if I was prompted frequently).

Lepidoptera: Suggest you clarify: on the day you encountered the message did you just get it the once, or did you get it many times? (eg. load a page, prompt with catptcha... change pages, prompted again)


Cloudflare's security will temporarily whitelist anyone who successfully completes a captcha.

I don't know what Cloudflare is actually looking at or tripping up on - and I'm not going to debate the merits of such software. The decision on what Cloudflare features are enabled/disabled is entirely up to Alex. All I'm saying is this is not an instance of a misconfiguration of Cloudflare, or any other kind of unintentional behavior.

I posted what I did to pre-empt any further discussion about a non-issue.

This thread has gathered quite a lot of attention, and a lot of eyes are on here looking for configuration issues with cloudflare that are degrading users' ability to use the site. I don't want to distract from that with issues that aren't actually issues at all.

If you want to take up the cloudflare security features any further than it's been taken up to this point, it would be a much better idea to start a new thread on the topic instead of derailing this one.

Yes, I got it several times. I entered the letters and it allowed me in, but when I came back perhaps 30 minutes later I was blocked again. I was always let in but some of those letter groups are hard to read. I had to reload them several times to find a group I could read. I suppose they're becoming more cryptic as word recognition software becomes more sophisticated. After a few times of this I gave up and came back later in the evening and there was no problem. None today either.

I ended up at this thread after I figured out CloudFlare was doing it and did a search on WP. I've heard of users blocking web sites but never a web site blocking a user so I was curious as to what was going on. I've been coming here for four years and never a problem before.

I got the "Host not configured to serve web traffic" error just now, and just a few times before it "went away".

For the past few days I too, have been getting "Offline Page" error messages for WP. Always after I have already started using the site, and gotten the front page going. I have been able to access a few posts and then that message pops up. It does give me the option to switch to a "live" session, though, and when I do that it works. I still don't like it, though. This needs to be fixed.

For the record I am using the Firefox web browser, and have no other browsers on this system. I only have a dial-up connection, so I am not about to try to install an alternate browser at this time.

If WP has switched to a different host, they need to see that things are properly configured so that this doesn't keep happening. This is a popular site with the members, and this site fills a need we can't get taken care of at sites like Facebook and Twitter. I have no interest in those other sites. I WANT MY WP! :lol:

I've been seeing these same offline messages the past couple of days.
