《纽约时报》官网被黑
The New York Times website has gone offline for the second time this month after what the company described as a "malicious external attack".
《纽约时报》官网本月第二次脱机，该公司将此次事件说成是“恶意的外部攻击”。
On its Facebook page, the Times said it was working to fix the problem, which appears to have started at 15:00 local time on Tuesday.
A technical problem knocked NYTimes.com offline on 14 August.
Analysts said evidence showed a group supporting Syrian president Bashar al-Assad was behind Tuesday's attack.
The website was partially back online three hours later, although some users still reported difficulties. During the suspension the New York Times published new articles on its Facebook page as well as a mirror site.
Mark Frons, the company's chief information officer, warned New York Times employees the attack was perpetrated by the Syrian Electronic Army, which backs Mr Assad, "or someone trying very hard to be them".
He cautioned staff to "be careful when sending e-mail communications until this situation is resolved".
Security experts said there was enough evidence to link the hacking group to the problems.
"The NYTimes.com domain is pointing at SyrianElectronicArmy.com which maps to an IP address in Russia, so it's clearly a malicious attack," Ken Westin, a security researcher for Tripwire, an online security company, told the BBC.
In a separate posting on Tuesday, the group also claimed responsibility for hacking Twitter's administrative contact information.
