DNS change request procedure documentation is missing

[rambo]

Change requests are done via issues here but we need to document what info should be in the request and in what format.

[tanelikaivola]

Best is to specify:

• Description of the change
  • For what purpose do you want change
  • If it's a main hacklab.fi-zone change change, provide much more information (or a link) about the service and the requirements
• Records to add / remove (if you know what you need)
  • Full DNS records that are required
  • Special requirements, for example: low TTL
  • Defaults:
    • $ORIGIN hacklab.fi (so you do not need to specify that in any of the records)
    • Class IN
    • TTL sane but somewhat low, likely somewhere in the range of 1h
    • MX priority 10
• Time frame when the change can happen.
  • Can it change right now: Are services already running and tested?
  • Must it happen before some time: Are you launching a service that needs to be up before given date?

For records, we are sanity checking them and sometimes refining/clarifying the request by providing alternative set of records. Or if the records do not make sense and no description is provided the request might be passed back to you to describe the intended purpose of the change.

For example:

Description:
A city specific mail server is being moved to a new host. Any other MX records should be removed.

Records:

• mail.kaupunki MX 100.100.100.100

Time frame:
Service is running. DNS change can proceed immediately and should be completed before 2019-xx-xx.
