I'm using http://SimpleCDN.com
They have a "Mirrored Bucket" which is an "origin pull".
How it works is I store my conent at mysite.com/abc.jpg and SimpleCDN pulls any requests from mysite.com, caches them in their CDN if not already in the cache, and display my content at simplecdn.com
I really like Origin Pull because I don't have to synch and/or FTP my content to their site, they simply pull it from my site (the origin) if it's not already in their cache.
However, recently, I've been having A LOT of problems with reliability and uptime of their service.
Question: Does anyone else know of a similarly priced CDN that offers "origin pull" CDN service that has great reliably and fast speeds at a reasonable price?
We have been using http://www.istreamlive.net. We tried Simple CDN, but their service is just terrible.

Trying to understand the benefits of CDN for a live company-wide town meeting. I understand how it would help for Azure blob streaming, but what about live video? If there's nothing to cache does a CDN offer any benefit?
The whole point of a CDN is content distribution over a large geographic area. If you are expecting viewers to come from all over the world then having a CDN would enable your content to be delivered from a closer location to that user.
It could have benefits for you even locally as well depending where you are. Some areas have a few Azure regions near them so it may well provide some benefit there.
One thing for certain is that you won't see a performance hit by using a CDN. Ultimately it's down to if the Azure Streaming Endpoint could support 10,000 viewers or if you'll need to CDN back it, I've done live streaming to more than that before without a CDN before the integration existed and it was fine but I would personally still look to make use of the CDN.
You can find more details on it over in this Getting Started blog post.

I'm new to bootstrap but could use some tips on getting started. From a performance perspective, is it better to import ALL of bootstrap using the MaxCDN, or download and host only the components I plan on using?
I do plan on customizing the appearance quite a bit. Thanks.
It is a difficult question, because the answer is: it depends.
Using external CDN has two advantages:
users which has visited site, which uses same CDN, will already have
JS and CSS in cache
you don't use your own network load
But there is also 2 main problems:
If user has blocked access t CDN (prox, firewall, CDN is dead) it is difficult to find it out
Most CDN doesn't have JS and CSS budles, which optimize request count (sometime ago I found CDN which serves bundles: http://piotrstapp.azurewebsites.net/cdn-bundles-are-avaliable/)
So to sum up: you have to check it yourself how fast your website will load using bundles, using CDN, etc. And then make a decision

I have a requirement of streaming millions of videos on demand. I read that CDN are the best option for that. But i recently came to know about IIS Smooth Streaming. Can anybody tell me, will IIS Smooth Streaming perform same as a CDN in streaming millions of files or does it has its own limitations (and is not a good option).
Thanks in advance.
IIS smooth streaming cannot ever come close to CDN. A CDN is a large distributed system of servers deployed in multiple data centers across the world, and the CDN takes the responsibility of sending the users the the nearest physical server when a request comes.
To stream millikns of videos on demand, CDN is your only hope !

sorry maybe a dumb question...
I'm curious if YouTube (for example) uses FTP to upload videos? I was trying to look around the source of the upload page and saw it seemed like they do some kind of plugin detection for Java, Flash, Silverlight, etc... does this mean they use one of those to have the client make an FTP connection and do an upload instead of doing a normal HTML form, HTTP upload?
Thanks for any enlightenment =)
No, they use HTTP for file uploads. FTP is considered non-secure protocol over the internet.
If ever you want to know what is happening between your computer and another one, I highly recommend downloading Wireshark ( http://www.wireshark.org/ ). This will show you exactly what is going on between the browser, any plugins and youtube.com.

i have a windows hosting provider and i am moving to another one. what is the best way to migrate a wordpress blog from one hosting provider to another ?
The Wordpress codex provides plenty of information on the topic of moving a Wordpress.
If you don't feel like reading through all of that, here is a far shorter guide, that covers essentially the same method.
