EarthLink today announced that it will be raising its monthly subscription fee from US$19.95 to $21.95, marking the first increase ever. The $2 price hike comes in the wake of America Online’s recent increase to $23.90. The new rate goes into effect on July 2 for new subscribers, and on August 1 for the company’s 3.1 million existing customers. Customers who sign up for service between June 1 and June 30, however, can get the $19.95 monthly rate for 90 days.
