Starting on November 15th, 2020, ThousandEyes will transition its infrastructure from the current data center to Amazon Web Services. The new infrastructure will use new IP address spaces. ThousandEyes customers who have IP address-based access control lists (ACLs) or firewall rules to permit Enterprise Agents, Endpoint Agents or other resources to communicate specifically with the ThousandEyes infrastructure will need to update those ACLs or rules. New ACLs or rules for the new addresses must be added to the existing ACLs and rules no later than November 15th, 2020. Any ACLs or rules with the old IP addresses must remain in place and active until at least January 31st, 2021.
