Beta site - 'Notes' page player layout issue with Firefox?

#4
Let me try to explain...

In the past (V1 & V2), our site was hosted on a single server. Well, three physical servers; one for processing, one for storage and one for databasing.

But one point of failure since all 3 of those servers (operating as one server) are housed at the same facility.

Now (V3), we are (to use really easy terms) mirroring portions of the site across dozens of servers, located at several global points.

So when you connect to our site, you're getting our central server which tells your browser where to go, and then your browser grabs the files (images, css, js) from whichever server is closest to your physical location.

So a viewer in Japan is going to be loading the site from a server in Japan. A person in the USA will get any of a number of USA hosted servers.

Why this affects your cache is simple: when I make a change to the CSS for example (as was the case with what you were seeing), my "real" server is the first to get the update. From there, all the dozens of other servers have to receive that update through a synchronization process. This is usually fairly fast (and I've developed ways to push it along even faster), but it can indeed take a bit of time.

So, if USA server #1 is synced to the latest version of the files, but Server #2 out in Japan is not synced yet, the guy connecting in USA will see a "newer" ... or "Current" version of the site, but the guy in Japan might see it differently.

I've been working on minimizing the impact of this (hence testing.css and the versioning system thereof), but it could, on occasion, result in some users in certain areas seeing old version of the files for a couple hours when I update them.

Makes sense now?

CDN means simply, "Content Distribution Network". We're distributing the content to multiple servers in multiple places. Simple as that. Smile

Enjoy the speed benefit!
