From a mobile operator in the UK, we saw an increase in TCP queries
starting on 20 Sept and ramping up. The current level (though not huge) is
almost double what it was before iOS 13 came out.
Thanks Greg. In terms of active connections we might be about the same,
but they seem to cycle open connections quite quickly. In terms of query
rates we are at about 4 times the normal rate here (for ones over TCP).
Thanks,
cheers, Greg

Hello,
We have recently observed an uptick in clients doing DNS queries over
TCP that started around the release date of iOS 13 and has grown since
then. Most of the qnames seem to be Apple related which points in that
direction.
Has anyone else seen the same in their environment?
Thanks,
