DNSSEC adoption

[Brown, William]

> One more thing should *in theory* not matter much. Personally, I'm not too happy about short TTLs. This trend is likely significantly undermining the stability and redundancy of the internet as a whole already.

In the days of limited, expensive hardware and slow links, long TTLs made sense.  Our one vCPU name servers are almost wasting power serving up several hundred domains.

To me it seems that a short TTL is going to let you route to a different server in case of outage in the absence of multicasting, etc. which may be overkill in some cases but a redundant server is adequate.  How does this undermine stability and redundancy of the internet?
