For those of you who have ATT Yahoo accounts, you should take note that your ATT Yahoo account (including snet.net, sbcglobal.net, and att.net) will not work with most Yahoo services after June 30, 2017. With some of these services, the ATT Yahoo account will need to be converted to a regular Yahoo ID. In other situation, it will be necessary to create or use a different Yahoo ID. Take a deep breath, the one major exception is Yahoo Mail. There will be no changes to how you access e-mail at this time. Please read this update from ATT
Connecticut residential internet customers should keep in mind that they have no connection with ATT anymore. The ATT e-mail accounts were not absorbed by Frontier. I want to reiterate my plea for ATT Yahoo e-mail customers to migrate to a Gmail or independently owned e-mail account. Yahoo is now owned by Verizon, a major ATT competitor. Further restrictions on Yahoo services, including mail, may be around the corner. Be proactive.
