I'm curious as to what's actually going on here. If I use dig ns fluent.ltd.uk @<cache-name> some caches give the 2 servers supplied by Nominet, others give the 3 servers from dns[1-3].fluent.ltd.uk (an extra round-trip). If I look on Google's 8.8.8.8 I get a random result with random TTLs. Perhaps the TTLs can be explained by Google's higher-level caching not coping with the conflict and leaving the individual servers to handle it, but their software is still producing two different results.
