CDN
The Content Delivery Network is used by all viewers. No viewer update was needed for CDN to work. It is a pure server-side thing.

Ciaran wrote about the problem he and others run into in: CDN Teething Problems & Meauxle Bureaux Should Be In Destination Guide. Some regions just refuse to render. Lots of textures fail to load. The usual leave and return tricks are not working. When these textures fail to load they FAIL to load and there seems little we can do about it.
The Lindens are aware of the problem and have posted on the SL Blog about the problem, what they think is causing it, and the hope it will pass with changes being made by both the Lab and the CDN provider. See: An Update on the [Second Life] CDN Project.
If you run into this problem, please file a JIRA report. Add your RL location (City, State, Country) and ISP name.
And like Ciaran I encourage you to check out the mole abode: Meauxle Bureaux.
