I can't find the link that advises its use right now, but this link talks about hosting ga.js on your server: http://www.google.com/support/googleanalytics/bin/answer.py?...
We support the option to host the javascript yourself, but before you can do that, you must check a box that says "I am hosting it myself". This flags that user/site in our database, so whenever we release updates to the javascript, we can automatically notify all of the users that there is a new version available.
We make a lot of minor modifications to the code but usually only announce updates when there are new features in it, or if certain features of the old tracking code may no longer work for some reason (this has never happened so far but I can't guarantee it will always be that way)
PS: I'm the Clicky developer, so that's why I know all this.
For your site limits, how is that counted? We're launching a new service with lots of aliases to essentially the same site (sub domains for different users), but on our server it's just one physical site handling it all. Would that be considered multiple sites in your system? If so, that may not work out (we'd quickly exhaust the 20 in your mega plan), but if not then we may be able use it. Thanks for the link!
PS. Looking at your Roxr page, sounds like you guys are doing pretty well with Clicky -- right on! :)
Several times recently, I've gone to my sites and it seems to never finish loading because Analytics is being slow again. It's at the foot of the page and installed correctly, but since it doesn't finish or close its connection it keeps the loading icon spinning forever which makes some users think there's still more to come. The last thing any analytics package should do is decrease the speed perception of your site.
Simple solution:
a) We download and install the Javascript on our end -- less for Google to serve, so they can focus on just saving the data.
b) They email us whenever a new version of the Javascript comes out, so we can update our copies.
That's not so hard, is it? Analytics is a nice stats interface, but it doesn't feel like it's been improved much (except for a new skin) in a long time. Expecting the above to be fixed, even just by improving the speed/stability of their JS serving, is the least we can hope for really.
