ACME maintenance and IP change

Scheduled for Aug 4, 10:00 - 15:00 UTC

Scheduled

We will be upgrading the load balancers used by the ACME service. No service impact is expected however there is the possibility of minor interruptions due to the work being performed.
Please note that the IP addresses (both IPv4 and IPv6) will change as a result of this work, so customers are encouraged to ensure that any firewall rules are up-to-date as previously communicated. The IP ranges used for the Atlas primary data centre are available at https://support.globalsign.com/ssl/manage-domains/list-static-ip-addresses and the new IP addresses will remain within these ranges.

Note that this window only affects ACME - the main certificate issuance API will not be affected by this maintenance.
