In case you’ve wondered, when your Google Search Appliance license runs out, you’ll receive this message in the admin area:
The license has expired. You are in the grace period. The software will stop crawling, indexing, and serving in 14 days. Please contact Google to extend your license.
The GSA will keep working normally for two weeks, giving you a chance to get a new license from Google Enterprise to continue it’s service, or finalise plans for moving away from it if you’re not going to get a new license.
Please note: the Google Mini does not have a license that runs out. Once the warrenty period is over you it’ll keep running as long as the hardware holds up.
