Broadcast retention changes
After Twitch's acquisition by Amazon, changes were made to how long broadcasts (sometimes called VODs) were retained for viewing on the site. Previously, all partnered accounts had indefinite storage, while standard accounts had storage for a few days. This was then cut down to two months.
Changes To VODs On Twitch
Aug 06 2014 · Engineering, Tech
Our goal at Twitch is straightforward: deliver the highest quality video. This includes the ability to watch video on demand (VOD) on all of our platforms, not just the website.
In order to create a system that supports live and VOD across the globe and on multiple platforms, we need to make significant changes to the way we’re currently storing video. Today, we’d like to discuss what these changes are, why they’re necessary, and how they benefit the entire Twitch community now and in the future.
Looking at Viewership Data
We found that the vast majority of past broadcast views happen within the first two weeks after they’re created. On the days following, viewership reduces exponentially.
We also discovered that 80% of our storage capacity is filled with past broadcasts that are never watched. That’s multiple petabytes for video that no one has ever viewed.
Highlights, on the other hand, have much more value and longevity. Over their lifetime, highlights get 9x as many views as past broadcasts.
As for existing past broadcasts, beginning three weeks from today, we will begin removing them from Twitch servers. If you would like to keep your past broadcasts, we encourage you to begin exporting or making highlights of your best moments so that they’re saved for posterity.
Although most partner accounts have broadcasts deleted after 60 days, there are some exceptions. Most of these are esports tournament channels, but other channels may be excluded for reasons such as being culturally significant. Below is an incomplete list of these exceptions.

Archives will be made available later as WARC files in the archiveteam_twitchtv collection at the Internet Archive. You can access them by the Wayback Machine, but you'll need search an index to find the media files.
A work-in-progress searchable index is now available!

In June 2016, Twitch deleted a bunch of custom emoticons on the grounds of obscenity. (Seefor details.)
The emotes can be found in the backend at: https://static-cdn.jtvnw.net/emoticons/v1/<id number>/<size> where id number ranges from 1 to 103667(as of 20160622), with no leading zeroes, and size is 1.0, 2.0 or 3.0.
Note: sizes 0.5, 1.5, 2.5, 3.5, 4.0, 4.5 and 5.0 are valid as well, but return the same data for most(all?) emotes as the next highest available 'whole number' or the largest below that one, i.e. for 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, will match 1.0, 1.0, 2.0, 2.0, 3.0, 3.0, 3.0, 3.0, 3.0, 3.0 respectively)
All emote graphics and sizes (but not their associated chat 'shortnames' i.e. "<3" for emote #9, which cannot be easily determined) still existing in the backend system up to emote id 103667 were archived through Archivebot here; the resulting WARCs can be downloaded through the viewer.
