What is Cloudflare ? How does it help webmasters ?

FYI, regarding the "Mirage: image resizing" bug that randomly decides to hide images:
We confirmed this bug yesterday. We've fixed the issue, and we just need to push out the new code to production. That will hopefully be at some point today.
 
I've had a problem with CF that I've contacted support about regarding images that CloudFlare has decided to add a "visibility:hidden" tag to. For what reason, I have no idea, but some people complain that images can't be seen, and when I look at the source, it looks like this.....
Code:
<img style="visibility:hidden;" data-cfsrc="http://imagehoster.com/image.jpg" /><noscript><img src=" http://imagehoster.com/image.jpg " /></noscript>
I don't know what CloudFlare app or service is doing this, but putting the site into development mode and hard refreshing, doesn't seem to fix it, because the visibility property is added to the post content in the message, it can't be removed by disabling CF. You have to edit the HTML source of the message posted.

After a lot of trial and error, the problem seems to be with the beta version of "Mirage: image resizing", on the CloudFlare settings -> Performance Settings tab. It just started happening a few days ago. I reported the bug to CF, and immediately turned it off for all my sites. I won't turn it on again. Strange how "pausing" CF didn't turn off this beta feature for me. Once I forced the feature off myself, my images automatically started working again.
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?

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.

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.

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?
