Hi Karl,
Anyone know why the Bind query appears to set such a low UDPsize? -
We've nothing in our config setting sizes, or maximums.
Here's an answer:

Hi,
Thanks for the pointer - ok, yes I can see it's probably EDNS / Flag day
related etc. I missed that - probably as it's never caused us an issue.
Annoyingly a value of 1232 causes a TCP fallback to a server out of our
control that doesn't do TCP very well.
Even more annoyingly - all the 'flag day' / online test sites we can find -
it works with, and passes all the tests.
Which means even if there were a chance of getting the remote server fixed
it's going to get "well, it works everywhere else and the online tests say
it's a pass..."
Thanks again though,
-Karl
