I know. I’ve been blog­ging about a few new data cen­ters recently (Brazil, Sin­ga­pore, Lon­don). But don’t yawn yet! Our most recent addi­tion to the data cen­ter fam­ily pro­vides a dra­matic improve­ment in ana­lyt­ics response time.

As many of you may know, Inter­net users in China typ­i­cally see much faster page load time when the con­tent is served from within the coun­try. As a result, in-country data cen­ters can improve the user expe­ri­ence dra­mat­i­cally when com­pared to data cen­ters out­side China, like those found in Sin­ga­pore and Tokyo. For this rea­son we have been work­ing hard to estab­lish this most recent data cen­ter inside the world’s most pop­u­lous country.

Begin­ning imme­di­ately, if you have RDC-enabled data col­lec­tion (data is being sent to omtrdc​.net) all vis­i­tors to non-SSL pages will be auto­mat­i­cally routed to the Hong Kong data center.

How much faster is our response time for these vis­i­tors? Tests by third party mon­i­tor­ing tools indi­cate a response time reduc­tion of 66–85%.

Let’s go through a few fre­quently asked questions.


Q. Do any non-Analytics prod­ucts uti­lize this new data center?

A. Yes. Test&Target, Scene7 and AdLens all serve con­tent or enhance the vis­i­tor click-through time using this data center.


Q. What is RDC?

A. Regional Data Col­lec­tion. This fea­ture ensures site vis­i­tors are hit­ting the near­est data col­lec­tion cen­ter, thus reduc­ing page load time. We have regional data col­lec­tion cen­ters in San Jose, Dal­las, Vir­ginia, Lon­don, Tokyo, Sin­ga­pore, Brazil, and now Hong Kong. For more details on Regional Data Col­lec­tion, see this post.


Q. How much will this change improve over­all page load time?

A. Browsers request mul­ti­ple pieces of con­tent at once when­ever they can. Most pages down­load dozens of pieces of con­tent, so this change is unlikely to dou­ble your page load speed. How­ever, if you have an oth­er­wise snappy page, a change like this should be notice­able to site visitors.


Q. How can I tell if I’m using RDC-enabled data collection?

A. Find your data col­lec­tion domain. If it ends with omtrdc​.net, you’re on RDC. If your col­lec­tion domain ends with you’re own domain, you need to ping it to see if it’s mapped to omtrdc​.net or 2o7​.net (non-RDC). Here’s how to find your data col­lec­tion domain in Chrome (there are a few other ways).

1. Go to your web site in Chrome and then go to Chrome Menu > Tools > JavaScript Console.

2. With the Con­sole tab selected, type s.trackingServer and hit Enter.


3. What you see is the data col­lec­tion domain used on your site. If this ends in omtrdc​.net, you’re on RDC. If this is your domain, as shown here, open a Com­mand Prompt (Win­dows) or Ter­mi­nal (Mac) and type “ping [your col­lec­tion domain]”. If it ends with omtrdc​.net, you’re on RDC. If it ends in 2o7​.net, you’re not.


Q. How do I start using RDC?

A. Instruc­tions for migrat­ing to RDC are found in Site­Cat­a­lyst Help. Go to Site­Cat­a­lyst > Help > Help Home and type Tran­si­tion­ing to RDC for detailed instruc­tions.


Q. Will RDC improve report speed or just data collection speed?

A. Report speed is not affected by regional data col­lec­tion, it sim­ply improves response times for your visitors.


Q. Can I license my SSL cer­tifi­cate for fewer servers and have it installed in just the America’s, or just Europe, since most of my traf­fic is in one place?

A. No, selec­tive deploy­ments of SSL cer­tifi­cates are not cur­rently supported.
