The company said it chose to restore just the last six weeks of articles right now "in the interest of coming back up as soon as possible."
A full restoration of Instapaper will take a week, so users can expect access to the rest of their data by February 17 "at the latest." Instapaper noted that the reason behind the outage appears to be a system limit that was hit for its hosted database, which prevented new articles from being saved by users.
The company apologized for the outage in its series of blog posts on the topic. It also reassured users that they "haven't lost any data" that was previously saved on Instapaper, saying that "anything you've already saved to Instapaper is safe."
We pride ourselves on being a reliable service with minimal downtime (we were up for 99.3% of 2016), and know many of you rely on Instapaper every day. We apologize that this issue has resulted in an extended period of downtime.Last summer, Instapaper was acquired by Pinterest with the intent to use Instapaper to encourage Pinterest users to save more articles to the site. A save-for-later feature has existed for several years on Pinterest, but wasn't used very often by those on the popular pinning site.
Instapaper is available for free on the App Store. [Direct Link]
