Huffington Post chief technology officer John Pavley recently took to HuffPostLive to explain what caused the online outage when Hurricane Sandy hit New York.
Pavley explains that the problems started when one of the site's New York City data centres, located near Battery Park, was flooded by the storm at about 7pm on Monday evening.
This forced parts of the site offline, resulting in the tech team using the site's backup data centre in Newark, which itself encountered problems.
Pavley went on to say that all three separate circuits that transfer data to and from the data centre, which are designed to be redundant, went dead for as yet undetermined reasons.
Between Monday night and Tuesday morning, Huffington Post was accessible via a temporary site - status.huffingtonpost.com - with writers and editors relying on Tumblr, Facebook and Twitter to post stories and information during the storm.
Huffington Post is now relying on its Newark data centre, while the New York City facility is under repair.
