PORTLAND — Internet and phone service was disrupted in a number of locations in New England due to a power-related problem, according to a spokeswoman for AT&T.

The company worked with a third-party access provider to resolve the issue, according to Katie Goudey, a public relations account executive with the firm Duffy & Shanley.

Service had returned to normal before 4 p.m.

The problem was caused by damage to equipment of Sidera Networks, according to the spokeswoman.

Goudey said she did not know how widespread the problems were in Maine or which other New England areas were affected. She said the problems lasted for two hours for some customers.

Additional details were not immediately available.
