Out of Date .jdb Files
I maintain a stand-alone network that uses Symantec Endpoint Protection Manager 11.x for Windows XP. I normally go to the Symantec site weekly for the latest virus definitions which come in a .jdb file. The last couple of weeks, the page I normally go to points to virus definitions that are 1-2 weeks old. Sometimes, I go back to the same page later in the day and it's up to date.
Today, the .jdb link points to vd3a2822.jdb, which says it was created 08/20/2012. A co-worker in another state goes to the same page and sees vd3a4811.jdb whose creation date is 09/04/2012.
I'm guessing everyone doesn't go to the same physical site when they go to the website. Probably multiple servers to carry the load.
Is there a known time when these servers get updated? Is there a certain time of day/week that's best to go get these .jdb files?
