Teem will be upgrading several network systems causing updates to external IPs and removing support for TLS 1.1 from the Teem platform on 9/13/2020.
What is TLS 1.1?
TLS 1.1 (and previously deprecated TLS 1.0) is an out-of-date security protocol used by browsers, devices and servers. Standards bodies, security frameworks, browser creators (Google, Apple, Microsoft and Mozilla) and security minded organizations such as Teem have committed to removing support for these protocols in 2020.
How does this affect our account?
Any systems unable to communicate utilizing TLS 1.2+ will no longer be able to access Teem platform APIs (This could include applications you've written to interact with our API directly, push notifications from Exchange servers deployed behind company firewalls, or browsers accessing the Teem administrative web application)
What do I need to do?
Ensure that your browsers and any devices (tablets, large screen displays, etc..) or calendaring systems (e.g. Exchange) that communicate with the Teem platform are TLS 1.2+ capable by 9/13/2020.
Any firewall "whitelisting" the Teem platform by IP address should transition to domain name (app.teem.com, push.teem.com, devices.teem.com) or utilize the new IP addresses after 9/13/2020.
