One delay is the time for the mirrors to get the updates. Depending on how
cleverly they're set up, and how much material they need to pull from the
reference repository, this can take significant time after the release time
at the primary distribution sites. This problem occurs for almost all
mirrored software distributions of any size. And whatever the local mirror
for you is, it may have fallen behind.
