Planned Maintenance: Customer APIs (Domains, DNS, SSL)

Scheduled for Mar 17, 07:00 GMT  -  Mar 18, 12:00 GMT

Scheduled

We will be performing planned maintenance to implement security upgrades for our customer APIs. The following services will be impacted:

1.) DynDNS
The following DNS API functions will be unavailable during migration:
• Enabling Dynamic DNS
• Disabling Dynamic DNS (globally or for a specific bulk id)

The other endpoints will continue to work.

2.) KMS-MW (API Key Management)
The following operations will be unavailable via the Developer Portal (https://developer.hosting.ionos.com/):
• Creating new API Keys (Existing keys will continue to function)
• Revoking API Keys

Listing existing API keys will continue to work.

3.) API_ACCESS
The following use cases will be affected:
• API_ACCESS provisioning
• API_ACCESS deprovisioning

Requests made during this time will remain in a pending state and will be automatically retried. No impact on overall contract activation is expected.

All systems will return to normal operation once maintenance is complete, however temporary downtime is possible.

We apologize for any inconvenience this may cause.
