Megaupload users whose data is in limbo are to get help retrieving it from the Electronic Frontier Foundation.
The popular file-sharing site was closed down last month by the Department of Justice, which claimed it was profiting from copyright theft. An unknown number of legitimate users using the site to store their own data look set to lose it as a result.
The two companies which stored data on Megaupload's behalf, Carpathia Hosting and Cogent Communications, have no access to the data themselves.
But Carpathia says it's now supporting the EFF in efforts to retrieve it, and promises not to delete the data without warning.
"We have no immediate plans to reprovision some or all of the Megaupload servers," says chief marketing officer Brian Winter.
"This means that there is no imminent data loss for Megaupload customers. If this situation changes, we will post a notice at least seven days in advance of reprovisioning any Megaupload servers at www.Carpathia.com and www.megaretrieval.com."
The EFF points out that legitimate users were given no warning that their data was about to be locked up, and no advice on how to get it back. While the EFF doesn't have much idea itself, it's asking Megaupload customers to get in touch via the megaretrieval.com page.
"EFF is troubled that so many lawful users of Megaupload.com had their property taken from them without warning and that the government has taken no steps to help them," says EFF staff attorney Julie Samuels.
"We think it's important that these users have their voices heard as this process moves forward."
