1273008 - Lower DNS TTL for treeherder.allizom.org

Status: RESOLVED FIXED

(Infrastructure & Operations Graveyard :: WebOps: Other, task)

Description

[Ed Morley [:emorley]]

As part of bug 1176484, we'll soon be wanting to update the Treeherder DNS records to point to Heroku rather than the SCL3 instance. To make this switch easier on the day, it would help if we lower the DNS TTLs pre-emptively.

Please could the current 1 hour TTL for treeherder.allizom.org be lowered to 60 seconds.


Side note:
Is it expected that treeherder.allizom.org has an A record (pointing to 63.245.215.125), whereas treeherder.mozilla.org is instead a CNAME (pointing to treeherder.vips.scl3.mozilla.com)? I would have expected for either both to be CNAMEs or else both to have an A record.

Many thanks :-)

Hrm, dunno how that came to be. Replaced the A with a CNAME.
