Great thanks to all replies!
You really helped us to understand what is behind the traffic we see.
Let's see if or when we will do the algorithm roll-over.

I'm sure it would lighten your load if you ensured that even negative
replies from your servers can fit into UDP comfortably, ideally under
1232 bytes [1]. Many big TLDs take great care to fit, and my favorite
way would be algorithm 13 (ECDSA, e.g. in my .cz TLD) but there are
others. It's not so much about this particular problem you report, more
like generally increasing robustness.
