Skype has stopped operating since June 19 in June in most areas of Europe and in a few parts of the United States. Microsoft was struggling for nearly 24 hours to restore access to the service, especially in Continental Europe, where some users still could not connect.
Microsoft acknowledged that the Skype service had problems but did not report anything about the cause of the interruption.
Hacking Group CyberTeam took over the responsibility for Skype holidays, saying members of the company had hit the service and promised that other attacks would follow soon.
In a tweet published on 19 in June, CyberTeam says that stopping Skype was "just the beginning of a new era", with Valve's Steam service the next target.

At this point it is difficult to determine whether CyberTeam is indeed responsible for downtime of Skype due to a DDoS attack, or if the company is doing some fixes that when they're done everything will be back to normal.
“We've made some fixes and mitigated it problem. We are continuing to monitor and will release an update when the issue is fully resolved," Microsoft said on June 20 at 20:00 GMT.
Initially, the company said it knew the problems they were facing and claimed that it had resolved them a few hours later.
H application Microsoft's instant messaging service appears to be working for most users for now, although there are complaints on Twitter that the service is unable to send and receive messages.
