Submarine cable resilience
The estimated 1.5M kilometres of subsea communications cables underpins our global telecommunication services. This critical infrastructure faces serious challenges in the coming years.
Rolling the root key
The root key of the DNS is scheduled to roll on 11 October. How many DNSSEC-validating recursive resolvers have learned of KSK-2024 and incorporated it into their TA sets?
Opinion: The economics of AI
As spending on data centres, power, and computing capacity surges, the question is no longer whether AI delivers value, but who will ultimately pay for it.
One or two nameservers?
Do multiple dual-stack nameservers increase or decrease repeat DNS queries? The results of this experiment were a complete surprise.
What part of ‘No!’ is so hard for the DNS to understand?
At APNIC Labs we’ve been experimenting with understanding how the DNS handles requests to resolve nonexistent names to make the DNS more resilient to random name attacks.

The delicate art of cryptographic maintenance: When small certs break big chains
Around mid-2026, we began receiving user complaints about certificate validation failures. The failure wasn’t a single bug, but the collision of optimization and slow distribution.
Data synchronization
Distributed systems depend on synchronization, but every approach has tradeoffs. From full copies to delta updates, how do you choose the right method?
