There will be a DDoS implementation for ui.epcsdrfirst.com at 10 PM EST on May 29, 2024.
DrFirst will be migrating services from ui.epcsdrfirst.com to a new hosting platform, thereby changing the underlying service IP address.
Please review the changes carefully to ensure no disruption of services after the migration.
DNS Change:
This migration involves changing IPs for listed services’ DNS. DrFirst will reduce the DNS TTL (time-to-live) to around 30 seconds for quicker propagation so please ensure your DNS setup honors the TTL to avoid any issues.
IP Change: 1. If your networking team is currently whitelisting DrFirst at a domain level (e.g. *.drfirst.com or *.epcsdrfirst.com) then NO action is needed as the DrFirst domains are NOT changing. 2. If your networking team uses IP addresses for whitelisting DrFirst, then in addition to currently whitelisted subnets please ADD 2 more IP addresses (old and new IP listed below).
Environment: Production Current Subnet Whitelist Requirement: 207.117.57.0/24, 65.221.4.0/24 Additional IPs to be Whitelisted: 45.60.233.33, 45.60.233.35
DrFirst will NOT be shutting down the old IP addresses currently serving the URL to avoid any abrupt disruption of service but there will be a hard cut-off date communicated separately.
Please reach out to your DrFirst Account Manager or DrFirst Support for any additional questions or clarifications.
