[$] A DNS flag day

A flag day for DNS is coming on
February 1; it may have escaped notice even though it has been
planned for nearly
a year. Some DNS
servers will simply be marked as 'dead' by much of the rest of the internet
on or after that day, which means that domain owners need to ensure their
DNS records will still be available after that point. A longstanding
workaround for non-compliant servers will be dropped—mostly for better performance
but also in support of DNS extensions, some of which can help alleviate
security problems.
