I keep seeing a persistent complaint that some DNS caching operators 
ignore TTLs or otherwise keep records for longer than the TTL would 

I suspect this might be an urban legend since most DNS caching software 
doesn't even offer this as an option last time I checked.

Does anybody actually do this? Because it keep being brought up by some 
peopel as to why things like GSLB don't work.
