Ooh, I could murder a..... datacentre code repository? Wut?

Fast datacentre code deployment using modified bittorrent. Interesting read.

and apparently Facebook does a similar thing. (No link, just random forum posts).

What took them so long? People have been using BitTorrent for deploying software since at least early 2008...

If think the interesting thing (in the video on the twitter engineering article) is the way they've told bittornado to distribute stuff.

Rather than using many<-->many (and suffering the inter-server chatter / processing overhead) they've told it to go server1-server2-server3-server4-server5-server6-serverNth, which means they don't have processing overhead on each node (and twitter webservers don't go pear-shaped under the load). They also found out that over however many thousand servers, there's no real difference in speed.

So if someone injected / inserted a virus / malware / spyware into one of the machines / peers that were using the bit torrent client(s) then it would share this with other machines and hence the bit torrent clients ( Distribrute ) would act like a virus itself as it would share this with other machines etc ?

I suspect it'd fail the hash check. If you compromised the seeding server(s), you'd have more luck.
