Microsoft issues mea culpa to No-IP, but service reportedly remains down for many

The cause isn't yet clear, but more than 36 hours after Microsoft disrupted dynamic DNS hosting for millions of No-IP.com users, service reportedly remained down for many, and the main website was also unavailable.

No-IP users continue to post tweets such as this one and this one saying service is still down. No-IP representatives on Tuesday evening reported coming under a denial-of-service attack but went on to suggest it had no relation to continuing problems with domain name resolution, which Microsoft took over a day earlier under a highly controversial court order issued in a botnet takedown action.

"Please note the DDOS attack was only directed at our website, not to our DNS infrastructure," No-IP representatives wrote in a twitter message posted around 5pm California time. In a separate tweet about an hour earlier, they said Microsoft's claims that service was restored Tuesday morning were not true. The No-IP website was unavailable at the time this article was being prepared, and a spokeswoman didn't respond to an e-mail requesting comment. The spokeswoman has reportedly indicated Microsoft's attempts to restore service to legitimate users have been ineffective.
