back to article Skype still staggering after major blackout

Skype is the process of recovering from a major outage that left users across the world unable to log into the VoIP service on Wednesday. Many computers that act as supernodes, the systems that provide directory information on Skype, were taken offline "by a problem affecting some versions of Skype". As a result many Skype …

The joy of distributed architecture

Distributed architectures are wonderful when they work.

And let "God stand between you and harm in all the empty places where you must walk" when they go belly up and you have to find a way to fix them.

Reason to ditch skype

This supernode crap is what made me ditch skype years ago. My pc became supernode overnight, and began consuming my complete upload allowance.

I agree free stuff is give and take, certainly with a distributed environment, but saturating my internet connection without giving me *any* control over it was a bridge too far.

And anyway, skype is closed as hell, I find standard SIP compliant VOIP much better - pick any provider or client, or even run your own server :)

Flaw

Thsi seems to be a fatal flaw in skype to be honest distributed should be able to cope

Nope

It is a standard type of failure in distributed systems.

If a distributed system failure is triggered by exceeding a capacity threshold and if clients perform some form of service discovery this is unfortunately a standard feature. Positive feedback loop. N clients trigger a bug in a node, node falls over, clients go to next node adding M clients in the process. N+M bottles sitting on the wall... and so on

As a result distributed makes it only worse because you get all kinds of wonderful stuff starting from "standing waves" of collapse and finishing with dead zones. There is a way to design around each and every one of these, but it is not something people do before it has bitten them.

Yo yo

Was briefly up at Midnight this morning. Prompted me to reply to the last article about Skype with a "maybe it's okay" message. Then it promptly went down again.

It's saying "online" right now, was "offline" about 10 minutes ago. Wonder if it's going to stay up now?

Back online

I was down for about 18hrs. Came back online at 3:15 GMT.

Really scary stuff if this was caused by hacking or DDoS stuff

I bet someone somewhere is doing high fives after this!

Yeah but, no but,

I was quite amazed yesterday when some of my users reported the fault. Even though I could not connect (just like the rest of the world) I was still able to update Skype on my PC; now running 5.0 but still could not connect...

How strange?

Steve Jobs because he is evil.

Can't they just move it into The Cloud?

All this technobabble about "supernodes" seems awfully complicated. Surely that should be Somebody Else's Problem?

Great service record, especially considering the traffic loads

It's only when you lose something, it's value becomes appreciated.

So it is with Skype, a good reliable service that provides so much for so little.
