On its homepage, the Huffington Post blamed power outages triggered by Monday's storm for "technical difficulties" as it offered readers minimalist post-storm updates with no photos or links to other parts of its vast site.
"We are working around the clock to get the site back to normal," it said in a boldface editor's note.
The hip Manhattan-centric website Gawker and stablemates such as Jezebel and Gizmodo were also out of action overnight, although Gawker managed to restore minimal service using an old-school live blog format.
Buzzfeed invited its visitors Tuesday to proceed to the website's Tumblr, Twitter and Facebook accounts for fresh content, in the absence of homepage updates since Monday.
On its Tumblr account, Buzzfeed said it was told by DataGram -- an Internet service provider that also serves the Huffington Post and Gawker -- that it had sustained serious flooding during the storm.
