Following the lead of the campus, Google, and other industry leaders, IRIS will be ending support for the older security protocols TLS 1.0 and TLS 1.1 on the department web servers (e.g. people.eecs.berkeley.edu, www2.eecs.berkeley.edu, iris2.eecs.berkeley.edu, and any IRIS-hosted web site) on March 24, 2020. If you are using a modern web browser, you will not notice any changes.
UPDATE
[2020-03-23| robm ]
As previously announced, support for TLS 1.0 and 1.1 has been discontinued on all IRIS websites.
