PORTLAND, Maine — USA Internet, a Web hosting company with offices in Portland and Bangor, is in the process of restoring a server that crashed late Monday morning, causing 27 of its hosted websites to go offline.

“It failed hard and they had to replace it,” Dale Summers, a data center technician in Bangor, said of the server in Portland.

Summers said all of the websites are backed up on another server, and he is guessing the sites will go back online sometime tomorrow morning when the server is restored. But, the technician added, it’s hard to tell when exactly the new server will be ready.

“We don’t do a whole lot of Web hosting,” Summers said. “It’s hard for a small outfit to compete with Google.”

Dana Moos, an innkeeper at the Pomegranate Inn in Portland, said on Twitter that the inn’s website has been down for more than 24 hours. She was not available for further comment Tuesday afternoon.
