You don’t need quantum hardware for post-quantum security
Organizations have finite resources available to combat threats, both by the adversaries of today and those in the not-so-distant future that are armed with quantum computers. In this post, we provide guidance on what to prioritize to best prepare for the future, when quantum computers become powerful enough to break the conventional cryptography that underpins the security of modern computing systems.
Impact of Verizon’s September 30 outage on Internet traffic
On Monday, September 30, customers on Verizon’s mobile network in multiple cities across the United States reported experiencing a loss of connectivity. Impacted phones showed “SOS” instead of the usual bar-based signal strength indicator, and customers complained of an inability to make or receive calls on their mobile devices. AS6167 (CELLCO) is the autonomous system used by Verizon for its mobile network.

You can't do anycast for a stateful application without taking the split-brain problem into account. It's really difficult to apply broad "can" or "can't", "works" or "doesn't work" advice here since there really are no absolutes.

Works. Many of us have been using anycast at Internet scale for DNS for a couple of decades. I would go further than "works" and perhaps say "necessary".

gmail security is a joke
I don't have a favourite pet - I don't know my grandmother's middle name, and never did - I don't have a favourite colour - I've never owned a dog - Are pets ever really owned? - Doesn't that speak to the denegration of others based on species?

Measuring DNS Performance & Graphing Logs
From: "Joe Abley" Date: Thu, 21 May 2015 08:13:28 -0400 I think you're more likely to get good answers to your BIND-specific questions on the bind-users mailing list. See: BIND9 has the capability to produce a vast variety and volume of logs, and dealing with logs in general is something that there are solutions for. Maybe look at logstash/elasticsearch as a starting point. Other BIND9 users on the bind-users list will no doubt have advice about what types logs they think are important.
