So you deleted some photos that you had second thoughts about from your Facebook page. Don't count on them being gone!

According to an investigation by Ars Technica, photos deleted from Facebook are still on the social network’s servers three years later.

Facebook told Ars Technica that, while its older systems did not always delete user-uploaded content within a reasonable timeframe, it's in the process of moving to new systems that will ensure any deleted content is removed from its servers within 45 days.

"We have been working hard to move our photo storage to newer systems which do ensure photos are fully deleted within 45 days of the removal request being received," Facebook representative Frederic Wolens told Ars Technica in an e-mail. "This process is nearly complete and there is only a very small percentage of user photos still on the old system awaiting migration. … We expect this process to be completed within the next month or two, at which point we will verify the migration is complete and we will disable all the old content."
