Cloudflare being partially blocked

[nerotic]

It's actually working quite well. I contacted their support department and they sent me the following (this is just partial):

Could an admin take a look and see if something in the server config is in conflict?

Thanks

1) You have blocked one of CloudFlare's IP addresses on your server or
you have a .htaccess rule in place that limit connections from some
IPs. CloudFlare acts as a proxy, so it is important not to block
requests from its IP addresses. If you have blocked any of the
following IP addresses, you should remove them from the list or
whitelist them. CloudFlare's IP range includes:

Ports used by CloudFlare: 80 and 443 (for SSL).

204.93.240.0/24 (204.93.240.0 - 204.93.240.255)

204.93.177.0/24 (204.93.177.0 - 204.93.177.255)

199.27.128.0/21 (199.27.128.0 - 199.27.135.255)

173.245.48.0/20 (173.245.48.0 - 173.245.63.255)

If you are not running any blocking software on your own server, then
the most likely place the block is happening is with your hosting
provider. Ask them to whitelist our IP addresses below when connecting
to your network. You can tell them that you are operating behind a
reverse proxy and the correct visitor IP will be reported by the
X-Forwarded-For header, which they can use for abuse detection.

By whitelisting the IPs, you'll have fewer issues in the future.

2) You are running some sort of protection software like BadBehavior
or mod_security that are blocking CloudFlare's servers access to your
server. Please make sure you're using an updated version of Bad
Behavior and mod_security.

3) Your firewall has rules set in iptables that could be blocking
CloudFlare. Please check your firewall to see if CloudFlare is allowed
access and that CloudFlare IPs aren't blocked.

My site just went down completely about 10 mins ago. According to Cloudflare it has to be something on my end.

Did something just change on Chopin that would cause this problem?

The data in my previous post is their troubleshooting guide. If there is any reason that I shouldn't be using a service like this kindly let me know. I don't want to run into any suspension issues or a permanent ban.

There are evidently some issues with your server at the moment.
The issue has been relayed to admins. We'll try to keep you updated.

Thanks STP.

As a little gift for you here's some better Spanish for your footer:

"Por favor disculpa mi español malo, esta hecho por un traductor de máquina"

Here's a question...did the IP or A NAME records of the server change during the migration?

[stpvoice]

The nameservers should always map to the correct place, incase you're worried about your custom domain?

[nerotic]

Right, but Cloudflare is an transparent proxy and I have to configure not only the nameservers but the IP as well.

[stpvoice]

You may want to double check that once maintenance is completed. Things could change before then, and there's no point in you changing it only to change it back. But in theory, the IPs should stay the same.

[nerotic]

Of course

My site is just a testing site for me so it's not mission-critical. Doesn't stop me from being curious though ;)

[stpvoice]

Should be back up now. If it's still giving the default web page, flush your DNS and clear your cache one last time.

I noticed that it came back up....speed is awful but I'm guessing that's because it's still ramping up and people are probably pounding on their reload buttons
