I’ve not seen any mention about the upcoming DNS flag day on this list, so I thought I’d mention it here.

The current DNS is unnecessarily slow and suffers from inability to deploy new features. To remediate these problems, vendors of DNS software and also big public DNS providers are going to remove certain workarounds on February 1st, 2019.

You can read more about it at https://dnsflagday.net and there’s also a great presentation I saw earlier this week at UKNOF 42 at https://indico.uknof.org.uk/event/44/contributions/580/attachments/886/1082/UKNOF42-DNS-Flag_Day-2019-01-15-CA3.pdf that might be of interest.

I encourage you all to head over to https://dnsflagday.net (https://dnsflagday.net/) and test your domain and popular domains in your country to make sure they are all OK. sdnog.sd is OK! ;-)
