Re: Mikrotik DNS server issues with Amazon S3 - low TTL 60sec

I would upgrade, but this problem seems unsolvable since 2007???
This exact issue was fixed in ROS 6.11 after my report to Mikrotik Support.

It has also been discussed here: https://www.linkedin.com/groups/1616717 ... 6799951874

I never saw this issue from latest 5 and 6rc versions. So for me it looks fixed.
