I read an article last year on "Speeding up Stack Exchange" that talked in depth about the 'multi-tenancy' nature of the (then) Stack Exchange 1.0 sites. I tried finding that link again today, and instead found the Twitter Trackbacks for it. The article itself brings up a 404, and it leads me to believe that the posts from blog.stackexchange.com weren't ported over, or if they were, there aren't any redirects issued for them.
What is meta?
- Any Stack Exchange user can ask a question
- The community provides support, votes on ideas, and reports bugs
- Your voice helps shape the way Stack Exchange operates
You can view the old blog at http://stackexchange.tumblr.com/. I think the actual post you want is here: http://stackexchange.tumblr.com/post/459188139/speeding-up-stackexchange
We only migrated over the last few posts to blog.stackexchange.com, since they were the only ones actually still relevant in the new Stack Exchange.
