[dns-operations] Who Ignores TTLs ?

[Haygood, David]

I know our ISP was extending TTLs of records set with short TTLs. This ruined an email spam software we were using because the TTL was modified so it didn't match the expected value, the software would mark it a spam.

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

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.
