In my experience it doesn't request DNS again if request fails. Waits till TTL expires. Multiple A records are useful if you have all servers exactly synchronized (as request can go to any server) plus on the moment of server failing it will still doesn't help as IE will keep reconnecting to same IP.
Though I haven't tested multiple A records.
- tricknik 16y agoThanks, I'll look into this more. In the case of Mammatus response, the TTL would already be expired, so the only problem would be if it pinned for longer and didn't request again on failure.
