System Announcements

9 May 2017 - Planned System Maintenance

On Tuesday 9 May maintenance will be taking place for approximately two hours from 06:00 - 08:00 BST (UTC +1).

The following systems will be unavailable during this time and connections will be reset:

  • EPP
  • Web Domain Manager
  • Online Services
  • Domain Availability Checker
  • Searchable WHOIS
  • Business Intelligence
  • Testbed (Operational Test & Evaluation)

Changes being released during this maintenance window include changes to further standardise the UK EPP interface and changes to the gTLD domain:check response. 

From 9 May the following changes will be implemented.

  • UK EPP timestamps (crDate, exDate and update) are returned in UTC with the letter ‘Z’ on the end to denote this. Dates had previously been returned in the ‘Europe/London’ time zone but with no timezone indication in the output.
  • The schema namespace names used in errors will now match those used for reply. We had previously used ‘contact-ext’, ‘domain-ext’ and ‘secdns’ in errors; ‘contact-nom-ext’,’domain-nom-ext’ and ‘secDNS’ will now be used in common with reply entities.
  • The domain:crID and contact:crID fields in responses will be changed to show the tag name rather than the previous ‘created-by’ field. When we don’t have this information, this field will contain ‘UNKNOWN’.
  • The domain:upID field in responses will be changed to show the tag name rather than the previous ‘changed-by’ field. Where we don’t have this information, the field will contain ‘UNKNOWN’. This change will not be made for contact:upID as we don’t have the required data.
  • secDNS commands will require the secDNS schema to be declared at login.
  • Where a host has been marked as deleted, it will no longer be returned by a host:info command.

Users of UK EPP should ensure that their system are updated to accommodate these changes. These changes will be available for registrars in the UK testbed (OT&E) from 12 April 2017.

There will be a new field in the EPP XML response to domain:check commands for unavailability reasons.

The unavailability reasons will start to show for all registrars who do a domain:check in the following cases:


Domain status

EPP response


The domain is registered



The domain is reserved across multiple TLDs

<domain:reason>Reserved A</domain:reason>


The domain is reserved


Users of Nominet's gTLD EPP should ensure that their system can accommodate this additional optional information.

Also, following the successful launch of optional two-factor authentication (2FA) for registrars accessing Online Services, in 2014, 2FA will be mandatory for all registrars from 9 May 2017. More information on this can be found here
