This morning (Jan 26th) at around 10:15 a.m. PST, Microsoft began to experience another denial of service attack. As a result of this attack, some customers experienced intermittent delays in accessing our Web properties for two 15-minute periods in the late morning. We regret the inconvenience this attack has caused to our customers. Microsoft took immediate action to deal with the attack and restore normal operations. All sites were up and running normally by 12:30 p.m. Pacific time. This attack was similar to Thursday's attack, in which someone attempted to block legitimate access to our Web properties by flooding our network routers with large volumes of bogus requests. This attack was not related to the security or reliability of any Microsoft product. In fact, no Microsoft product was targeted as part of the attack. This attack was not an attempt at intrusion, and no customer data was compromised in any way. Microsoft's Web servers and other Internet services running on Microsoft products continued to operate normally during this event.
