Over the last several days Microsoft's websites (MSN, Hotmail, Microsoft.com, etc.) have experienced periodic blackouts. Both administrator errors and denial of service (DOS) attacks have been blamed.

Does Microsoft take security seriously enough?

Do these events signal a neverending disruption of Internet services from hackers and virus creators?

i think microsoft takes security seriously. but the reason is that microsoft is widly used brand in internet world.

theirfore every hacker wants to attack on them. but it is also true they have security loopholes in their systems.
