Have you been dragging your feet when it comes to updating your web browser? If so, shame on you! Also, you have until November 15 to join the rest of the tech world and ditch Internet Explorer 8 or else you’ll lose access to your Gmail, Google Calendars and any other Google apps you use.

After the launch of IE10 Google plans to stop supporting IE8 (and everything below it). This is actually common practice, as Google focuses on the two most recent versions of all major browsers. Here’s their explanation:

As we announced last year, we support the latest version of Google Chrome (which automatically updates whenever it detects that a new version of the browser is available) as well as the current and prior major release of Firefox, Internet Explorer and Safari on a rolling basis. Each time a new version of one of these browsers is released, we begin supporting the update and stop supporting the third-oldest version.

The newest iteration if Internet Explorer comes out on October 26 so that gives users roughly three weeks to make the change.

So if you notice a message in your Google apps urging you to update your browser, you might want to listen. (Also, you’ve been warned. And testers, this is not a bug.)
