Which languages to download or install For example, English en-us and French fr-fr. For more information, see Deploy languages for Office Which edition of Office to download or install. For example, the bit version. Valid xml values are "32" and " We recommend bit on computers that have 4 gb or more of memory. But you should assess application compatibility and other factors that might require you to use the bit version.

Tip If you want to specify advanced configuration settings for your CDN endpoint, such as large file download optimization , you can instead use the Azure CDN extension to create a CDN profile and endpoint.

You can use the best practices outlined in Managing Office endpoints to ensure that your network configuration permits client browsers to access the CDN directly rather than routing CDN traffic through central proxies to avoid introducing unnecessary latency.
You can also read Office Network Connectivity Principles to understand the concepts behind optimizing Office network performance. The CDNs in use by Office are always subject to change and in many cases there are multiple CDN partners configured in the event one is unavailable. The primary CDNs used by Office are:. There are many factors involved in measuring specific differences in performance between data downloaded directly from Office and data downloaded from a specific CDN, such as your location relative to your tenant and to the nearest CDN endpoint, the number of assets on a page that are served by the CDN, and transient changes in network latency and bandwidth.
The following screenshots illustrate the difference in download speed between the native file location in Office and the same file hosted on the Microsoft Ajax Content Delivery Network. These screenshots are from the Network tab in the Internet Explorer 11 developer tools.
These screenshots show the latency on the popular library jQuery. To bring up this screen, in Internet Explorer, press F12 and select the Network tab which is symbolized with a Wi-Fi icon.
This screenshot shows the library uploaded to the master page gallery on the SharePoint Online site itself. The time it took to upload the library is 1. The second screenshot shows the same file delivered by Microsoft's CDN. This time the latency is around milliseconds. This is a large improvement and shows that a whole second is shaved off the total time to download the object.
We take great care to protect the data that runs your business. Requests for data in the Office SharePoint CDN must be referred redirected from your Office tenant or an authorization token will not be generated. Additional features are turned on by default to make delivery of large files faster. When a large file is requested, the CDN retrieves smaller pieces of the file from the origin.
After the chunk arrives at the CDN edge, it's cached and immediately served to the user. The CDN then prefetches the next chunk in parallel. This prefetch ensures that the content stays one chunk ahead of the user, which reduces latency. This process continues until the entire file is downloaded if requested , all byte ranges are available if requested , or the client terminates the connection. For more information on the byte-range request, see RFC The CDN caches any chunks as they're received.
The entire file doesn't need to be cached on the CDN cache. Subsequent requests for the file or byte ranges are served from the CDN cache. If not all the chunks are cached on the CDN, prefetch is used to request chunks from the origin.
This optimization relies on the ability of the origin server to support byte-range requests; if the origin server doesn't support byte-range requests, requests to download data greater than 8mb size will fail. The default complete cache fill feature enables the CDN to pull a file into the cache when an initial request is abandoned or lost. Complete cache fill is most useful for large assets. Typically, users don't download them from start to finish.
If you'd like it on google, please raise it with the google bros - :. Looks like bootstrapcdn is the popular choice, but for those wanting to use cdnjs. There's an error in the minified JS link above. The extension should be. Skip to content. Star k. New issue. Jump to bottom. Labels feature. Copy link.
It's also not versioned nor guaranteed to not move. Needs, CDN, badly, please.
