Scheduled
IMPORTANT: This event will introduce new IPs for interfaces using ZOLL's Remote Downloader. Interfaces using Redox are not affected.
For continuity of Remote Downloader interfaces: * If you use DNS/URL-based allow listing, whitelist FQDN *.emscharts.com * If you whitelist IPs, get the current list via command prompt by entering "nslookup whitelist.emscharts.com". This will always reflect the current required IP addresses.
Start: Wed April 22, 2026, 3:00 AM ET End: Wed April 22, 2026, 6:00 AM ET
Remote Downloader users, please: * Implement any required IP whitelist changes before April 22. * Restart your interface after the scheduled maintenance has ended.
Thank you, The ZOLL Data Systems Team
