More DNS server rebuilds

2018-12-19 - News - Tony Finch

As announced last week the remaining authoritative DNS servers will be upgraded this afternoon. There will be an outage of for several minutes, during which our other authoritative servers will be available to provide DNS service.

The primary server will also be rebuilt, which will involve reconstructing all our DNS zone files from scratch. (This is less scary than it sounds, because the software we use for the hourly DNS updates makes it easy to verify that DNS zones are the same.)

These upgrades will cause secondary servers to perform full zone transfers of our zones, since the incremental transfer journals will be lost.
