Description

Please be informed that this information is applicable exclusively to users of SiteBacker, Traffic Controller, Simple Failover, and Simple Load Balancing. On July 11, 2025 (or after), we will be bringing the Toronto Traffic Management probers into service. These will be part of the North America East group. If you have any Traffic Management (SiteBacker/Traffic Controller/Simple Failover/Simple Load Balancing) pools that are testing or monitoring IP addresses that are not open to the Internet, you will need to add the following IP addresses to your whitelist: 156.154.84.153 2610:a1:303c:128::153 156.154.84.154 2610:a1:303c:128::154 Our current list of Traffic Management probers are listed here: https://ultra-portalstatic.ultradns.com/static/console/docs/Traffic_Management_IPs_for_Probing.html It will updated in the near future to include these new addresses. If you do not use any of the above products ((SiteBacker/Traffic Controller/Simple Failover/Simple Load Balancing), the above notice does not apply to you. If you do use the above products but only monitor IP addresses open to the Internet, it is unlikely that you need to make any changes. That said, if you have any monitoring on your side that can block external addresses that do repetitive tests, you likely already have a whitelist for Traffic Management probers and will need to update it by adding the new values. What are the consequences of needing to update whitelist and not doing so? Your configured Traffic Management probes could generate alerts due to tests from Toronto not completing successfully. This could even lead to a managed record failing over to its backup records (or the All Fail record if all numbered priority records are in failure). That said, SiteBacker default settings require at least two monitoring locations to be failing tests for failover of a record to occur. In other words, communication issues between our Toronto site and your monitored endpoints would not by itself by sufficient to trigger a failover to a backup record. There would need to be one other location already in failure for a new failure from Toronto to be sufficient for trigger a failover to backup records.

Description

We will be performing database maintenance on 13th July 2025 from 4:30 AM UTC to 10:30 AM UTC. For a few minutes within the maintenance window, UltraDNS Managed Services Portal (https://portal.ultradns.com) and the REST API (https://api.ultradns.com) transactions may encounter errors and need to be attempted again. In addition, Site Backer, Traffic Controller fail over events and Primary domain propagation may be delayed for up to 10 minutes during the maintenance period. There will not be any impact to DNS resolution, as existing data will continue to resolve throughout.
