I have several blocked outgoing connections to- server-54-240-166-136.lhr5.r.cloudfront.net, most are on port 80 but some are on port 0, and I am just wondering what this is and what it is for, also if I should allow it.
Thanks
Gordon

Re: Outgoing connections to cloudfront
They are in my server logs as blocked outgoing connections, not really sure what is causing them, I also had some outgoing connections to pay pal blocked as well, and they were at roughly the same time, though there a whole bunch to cloudfront

Re: Outgoing connections to cloudfront
Cloudfront is a CDN run by Amazon AWS, and is a place where *many* websites host common assets, especially images and javascripts, and all kinds of other things.
PayPal might be serving images from servers there.
You might be using addons which access resources hosted there.
The only thing Zen Cart v1.x uses on cloudfront is when you login to your admin it checks what the latest version of Zen Cart is, and tells you if that is a newer version than the one your store is reporting, thus inviting you to do an upgrade. It's a single hit to a single tiny .txt file.
Generally speaking it is pointless to be blocking port 80 or port 443 access to cloudfront, as usually there is important information there that your site is needing.
Not sure why you're doing that blocking at all really..
