If you're 65 or older, or have two or more underlying health conditions, you're newly eligible to sign up for a coronavirus vaccine appointment in Massachusetts.
But if you logged on to the state's website to book an appointment Thursday morning, you would have seen an error message. Just after 11 am, the official state Twitter account posted that all appointments at the mass vaccination sites in Springfield, Danvers, Natick and Dartmouth had been booked, and apologized for "website challenges."
