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.
