The website for the New York Times was inaccessible for some users Tuesday, apparently as the result of a malicious attack. Tuesday’s outage comes less than two weeks after the site suffered an outage that lasted approximately two hours.

The newspaper’s site was inaccessible for some — but not all — users starting at 3 p.m., and many users took to Twitter to ask if others were having similar problems reaching the site.

A Twitter account for the Syrian Electronic Army also claimed it pulled a similar attack on Twitter. Twitter spokesman Jim Prosser confirmed that the company is looking into the report.

The New York Times confirmed that its site was having problems, and company spokeswoman Eileen Murphy said that the outage was likely due to a “malicious external attack.”

“The site is down for some. We are working to fix the problem. Our initial assessment is that this is most likely the result of a malicious external attack,” she said.

Evidence of the attack could be seen through the domain name system, or DNS, entry for the New York Times. The DNS is essentially like a phonebook for the Internet that tells computers how to reach certain sites. The entry for the The New York Times was pointing to companies based in Moscow and Syria.

Sophos security researcher Chester Wisniewski confirmed that the name servers listed on the directory entry are controlled by, and that the site does appear to be under attack.

“Depending on where you are in the world, visitors to the Times are being redirected to servers in Syria that appear to be operated by the Syrian Electronic Army, a group infamous for attacking Western media organizations,” Wisniewski said in an email.

The New York Times continued to publish stories despite the attack by offering users an alternative way to reach its site.

The New York Times outage follows other site issues the newspaper experienced two weeks ago. On Aug. 14, the company confirmed that its site had been affected by a “internal issue” that took the publication’s website offline for approximately two hours.

The Times has not offered further details about what may have caused that outage, but told The Washington Post at the time that it had “no reason to believe” the issues were the result of an outside attack.

August has been a particularly bad month for prominent outages. One day after the New York Times outage, several news websites, including The Washington Post, were affected by a breach at the third-party content provider Outbrain, which redirected some visitors to sites promoting the online activist group, the Syrian Electronic Army.

Google and Amazon have both been hit with technical problems that took down their websites. An Amazon Web Services outage this weekend also affected the performance of services including Netflix, Instagram and Vine.

Last week, Nasdaq was also forced to halt trading for three hours after a “technical glitch.”

There is no indication that these outages are connected.
