Zone file production
Zone files for the no zone and all subzones are generated automatically at the times listed below, and are then published in Norid’s domain name service. All times are local (CET) time.
|Monday – Friday||Saturday, Sunday|
|12 am, 4 am, 8 am, 10 am, 12 noon, 2 pm, 4 pm, 6 pm and 8 pm||12 am, 4 am, 8 am, 12 noon, 4 pm and 8 pm|
Complete publishing to Norid’s DNS servers takes up to half an hour.
Only zones witch actual changes are published after each generation.
What if publication has not been performed as scheduled?
To ensure that only flawless and consistent zone files are published in DNS, a large number of automated checks are performed on each zone file before publishing take place. The checks include thorough verification of both DNS and DNSSEC data. If the checks reveal inconsistent data, or the number of records which changes in a zone file is larger than an upper/lower limit, the automatic publishing process will be terminated, and an error message will be generated internally. A Norid technician must then analyze and determine what caused the problem, resolve it and then manually start the publishing process in automatic mode.
This strategy is chosen to prevent zone files with errors or with unexpectedly many changes to be published.
If you monitor DNS and discover that zone files are not published regularly and as expected, the reason might be that our checks have detected a possible problem and that the automatic publishing process has been terminated.
If a problem arises during normal working hours, it should normally within a short time. If a problem arises outside normal working hours, resolving might take longer time.
