Machine learning is a rising star in the compute constellation, and for good reason. It has the ability to not only make life more convenient – think email spam filtering, shopping recommendations, and the like – but also to save lives by powering the intelligence behind autonomous vehicles, heart attack prediction, etc. While the applications of machine learning are bounded only by imagination, the execution of those applications is bounded by the available compute resources. Machine learning is compute-intensive and it turns out that traditional compute hardware is not well-suited for the task.
Many machine learning shops have approached the …

Recent headline grabbing DDoS attacks provoked heated debates in the DNS community. Everyone has strong opinions on how to harden DNS to avoid downtime in the future. Is it better to use a single DNS provider or multiple? What DNS TTL values are best? Does DNSSEC make you more or less exposed?

These are valid questions worth serious discussion, but tuning your own DNS server settings is not the full story. Together, as a community, we need to harden the DNS protocol itself. We need to prepare it to withstand the toughest DDoS attacks the future will surely bring. In this blog post I'll point out an obscure feature in the core DNS protocol. It is not practical to use this "hidden" feature for DDoS mitigation now, but with a small tweak it could become extremely useful. The feature is currently unused not due to protocol problems - it's unused because of the DNS Top Level Domain (TLD) operators' apathy. If it was working it would reduce DDoS recovery time for the DNS servers under attack.
The feature in question is: DNS TLD glue records. More specifically DNS TLD glue records with Continue reading
