Web Server Security Upgrades Require Modern Web Browsers

Starting Dec. 2, at 6 a.m. PST, University IT (UIT) will perform security upgrades to Stanford’s shared web servers (web.stanford.edu). If you use a significantly older version of a web browser, you may be unable to access the upgraded websites.

To avoid disruptions, we encourage you to ensure your browser is updated to the latest version as soon as possible. Most browsers have a menu item that displays the version you are currently using.

Before upgrading browsers, please review UIT’s browser recommendations to ensure the latest version is compatible with Stanford's administrative applications.

These are the required versions of popular web browsers:

• Chrome, v. 33 or later (latest version is 92.0.4515.157)
• Firefox, v. 34 or later (latest version is 83)
• Internet Explorer 11 or later
• Edge Any (latest version is 92.0.902.67)
• Safari 7 or later (latest version is 14.1.2)

The current shared web servers (web.stanford.edu) use older security protocols known to be susceptible to online attacks. To minimize risk, University IT (UIT) will upgrade the shared web servers to improve their overall security by introducing a higher level of data encryption.

This update will affect all websites hosted on the central web servers.
