From Russia, with Love ? Exploit code was published by an anonymous user on securitylab.ru and this caused Skype massive disconnections today.

I agree with George Ou who ust published his view on the Skype Outage. He also confirms that Skype is still down and states that a Published DoS exploit may be culprit. Important enough to quote here :

" Valery Marchuk of SecurityLab.ru may have an explanation for this world wide outage for Skype.  Marchuk posted the following message on the full disclosure mailing list: Valery Marchuk: On SecurityLab.ru forum an exploit code was published by an anonymous user.  Reportedly it must have caused Skype massive disconnections today. The PoC uses standard Skype client to call to a specific number. This call causes denial of service of current Skype server and forces Skype to reconnect to another server. The new server also "freezes" and so on … the entire network. " source : ZDNET / GEORGE OU.

Not very reassuring if you read all this. Indeed a developing story. If the above is a correct observation then there are more problems ahead.

And yes. Skype is still down. I could logon briefly this afternoon, but now the problem is back again. Nothing is really solved. The update to 3.5.0.xxx did not help a lot, at least not for me. I simply cannot logon. Something is still broken.

Think now about some companies that use Skype… Imagine if had been somebody that had supplied a bunch of skype-phones or skype gateways to SME's. Luckily I just looked at the whole market and observed what is going on. Time to read the SLA and EULA..

All papertrail, in the end there is no SLA on earth that can help in these kind of scneario's. Skype is huge VoIP provider and they got a huge problem now. Credibility is one of them. For starters.
