After approximately 8 am on Thursday, August 16, 2018, wireless users (eg. typically cell phones connecting to the wireless WIFI network) may be prompted to confirm to accept a new certificate. Wireless authentication systems will switch to the newly renewed certificate indicating either Thawte or DigiCert depending on the wireless client. Depending on the certificate trust setting of the device, some wireless clients may prompt for confirmation to accept the new certificate, and others may simply accept the new certificate transparently requiring no user action. If you see a request to confirm the new certificate as described, it should be safe to accept it on your device.
