Just wanted to let everyone know, that a new version of MemcacheD has been released. We will be rolling this out to the memcache nodes during the week of July 20th to 24th. This should have very little impact on the stability of the website; however users may see a slight increase in load times as the cache is re-populated with entries.
The software has been tested and verified to be working just fine with the application; so we perceive this to be a very minimal risk in regards to updating, and the stability of the website.
***EDIT*** This upgrade has been completed. Everything is running smoothly... ***EDIT***
