Skype stopped working since the day before June 19 in most regions of Europe and in a few regions of the United States. Microsoft was fighting for almost 24 hours to restore access to the service, especially in Continental Europe, where some users still could not connect.
Microsoft recognized that the Skype service had problems, but said nothing about the cause of the outage.
The Hacking Group CyberTeam took responsibility for the Skype outage, stating that its members hit the service and promised that very soon other attacks will follow.
In a tweet posted on June 19, CyberTeam reports that the Skype outage was “only the beginning of a new era”, and that Valve's Steam service will be the next target.

At this point it is difficult to determine whether CyberTeam is truly responsible for the Skype downtime due to a DDoS attack, or if the company is making some fixes that when completed everything will return to normal.
“We have made some fixes and mitigated the problem. We continue to monitor and will publish an update when the problem is completely resolved”, Microsoft said on June 20 at 20:00 GMT.
Initially, the company stated that it was aware of the problems they were facing and claimed that it had resolved them a few hours later.
The Microsoft instant messaging app appears to be working for most users at the moment, although on Twitter there are complaints reporting that the service cannot send and receive messages.
