Re: VeriSign's rapid DNS updates in .com/.net

Matt, others, I am a quite concerned about these zone update speed improvements because they are likely to result in considerable pressure to reduce TTLs **throughout the DNS** for little to no good reason. It will not be long before the marketeers will discover that they do not deliver what they (implicitly) promise to customers in case of **changes and removals** rather than just additions to a zone. Reducing TTLs across the board will be the obvious *soloution*. Yet, the DNS architecture is built around effective caching! Are we sure that the DNS as a whole will remain operational when (not if) this happens in a significant way? Can we still mitigate that trend by education of marketeers and users? Daniel
