This weekend we’ll be continuing with upgrades to our primary DNS infrastructure. This will result in faster load times and more reliable service, but it does require a reload of all zones on our system. We will be staggering these reloads across our anycast clusters to prevent downtime. Zones will continue to resolve for the duration of the window, however any external monitoring services may report brief service interruptions with individual nameserver clusters as the system reload is carried out.
Should you have any questions or concerns about this please contact us.
