What is Cloudflare ? How does it help webmasters ?

FYI, regarding the "Mirage: image resizing" bug that randomly decides to hide images:

We've filed a bug for the Mirage issue. Pausing CloudFlare can take 5-10 minutes or so to go all the way through. Did you wait that long before checking again?

I just wanted to highlight that CloudFlare and OpenDNS have teamed up to stop the DNSChanger malware from impacting internet surfers.

Good to hear. Sorry I didn't catch it before making the other post. The image optimization features are still somewhat beta & making tweaks to them as customers report issues to us.

Added to my 3 sites already

CloudFlare is better day after day.
Congrats.

Hi Bashy,

Much appreciated. Here's to helping some unknowing net citizens!

Hi Dinh,
Thanks. And you have been with us for quite some time, both during good and bad. Much appreciated...

What this man said. Currently hosting about a dozen domains on Cloudflare, still loving it. Keep up the good work.

After using CloudFlare for over a month on all our key sites, I see clear improvements in loading times and more traffic. It's also helpful to get warnings when someone's computer is compromised. One of my colleagues got the prompt, and is busy running anti-malware software as a result.

All told, I'm extremely pleased with this service.

Hi Gene,

Thanks. I wish people realized that there are real reasons a challenge page is thrown up to some visitors...really done for a reason (data sources). A lot of people freak out at times because of the challenge page.

Much appreciated. And I believe you sent in that suggestion as well (sent it to the engineer...don't know if what you requested is possible...but still sent it along).

Decided to try it again with my brother's wordpress site for his landscaping business, the only problem I have is Ipower's domain management apparently doesn't understand or like, the Name servers for cloudflare, hehe

It won't accept the cloudflare Nameservers, stating:

Records for xxxxxxcom could not be updated. The nameserver you chose may not be a valid nameserver. Please verify with the provider and try again

What are the nameservers in question? I have really only seen this happen if there is a typo in the nameservers when adding at the registrar.

Today I decided to test and install cloudflare in my community, she has access to 95% of Brazil's ... let's see how it behaves.

Hi FabioCesar,

Thanks! Some quick tips that help a lot:

A lot of users have requested customizing CloudFlare error pages in the past. I did want to advise that this is now available to paid CloudFlare plans (Pro or above).

Directions for customizing CloudFlare error pages

A couple of quick notes related to CloudFlare:

1. We have released two new datacenters in Atlanta and Sydney (more on the way).
2. We have also released the ability to purge a single file.

Hi damon, figured i'd save you a ticket and ask whether this means there's new IP ranges to be added to the X-Forward-For whitelist.

No new IPs (would have mentioned that). The full & current list for CloudFlare's IPs.

So the single file purge. If I change one css file on my site, I can just have that file deleted/purged from the cache on CloudFlare to have the changes recognized?
