Skype Outage Special Update

Your favorite VOIP Softphone/service, Skype is currently facing a outage. It's already a breaking news in the media and across the VOIP world. We got some latest updates on Skype Outage.

since yesterday night (singapore time), Skype started facing issues related to login. Earlier some people spread rumours such as Skype's server aint working, Skype is out of business but once the picture was clear it wasnt the case. People just love to hype the scene.

The Real issue was because of a deficiency in an algorithm within Skype networking software. This controls the interaction between the user’s own Skype client and the rest of the Skype network. We at VOIP Guide feel, the issue was related to authentication algorithm used on their P2P networ which uses a very speculative "supernodes" technology. If anyone of you have read our very interesting article on "skype supernodes and vulnerability", you would probably know how insecure skype could be.

What possible went wrong at Skype:

All Skype users possess digital credentials, it is possible for any Skype user to verify the identity of any other Skype user. This process is called authentication: the proving of each party's true identification to the other.

Now Since Skype uses Hybrid P2P, its essential to know identification for each party in order to verify a user and transmit data as legitimate packet. If skype server side authetication algorithm is broken, the authentication can't be completed and that could lead to anyone breaking into skype system and acting as a "Skype" user and send unencrypted data over skype network leading to more serious hacking event.

To avoid such thing from happening, Skype has currently disabled authentication for all users and working to fix the algorithm.

How they are recovering:

Villu Arak At Skype posted on their blog, that We’re on the road to recovery. Skype is stabilizing, but this process may continue throughout the day.

Latest Update from VOIP Guide:

Here in singapore, we still can't access Skype. Even after repeated attempts, can't login to Skype. I suggest everyone to give your latest update and let us know if skype is working for you.

Although, Skype had disabled the downloads. It seems the downloads are working now, If you don't have a latest version of skype maybe you can download it now
