As someone who has also deployed GSLB's with hardware applicances I would also like to know real world problems and issues people are running into "today" on modern GSLB implementations and not theoretical ones, as far as I can tell our GSLB deployment was very straight forward and works flawlessly.
since "works flawlessly" could just mean that you don't have any reported problems with the technology -- no complaints from your users, no bugs logged with your vendor, etc, i have two bracketing questions. first, have you measured the improvement you got -- in terms of min/max/avg/stddev of TTFB/TTLB (time to first byte / last byte) with the appliances turned on vs. turned off? second, have you measured the dns damage your gslb might cause or contribute to, due to things not responding to unhandled QTYPES (AAAA comes to mind) or use of abnormally low DNS TTL? i'm not as much interested in whether a technology causes no problems for its operator as whether its cost:benefit is worthwhile to the internet community. -- Paul Vixie
