Whatever caused the edit triggered purge to get missed needs to be fixed. I have no doubt that there are a few code pathways where some needed purges may be missed, but it seems that users have adapted by adding a fair amount of paranoid pointless refreshing and purging. Better to make the problems more expose so they can be found and fixed.
Does it take such a negligible amount of time for Squid cache purges to occur? How long is it from the time the purge code is run on the application servers until the Squids in all clusters have discarded the old cache?
A fraction of a second, mostly determined by the propagation delay of the packet to reach the Squid.
