It depends on kind of patch, when they add new content then really often many bot offsets change. They have to trace all that changed and remplace it by the new ones wich require Low to extreme work depending on kind of patch.

So.. usually it takes 30 min -1 hour when it is a small patch

for big patch .. cant say .. it can take up to 1-2 day ( i rarely have seen it down more then 1 day).

Also.. when the update takes to long(rare) they usually add 24 hours to your subscription.
