Skype

What We Learned From the Skype Outage

August 20, 2007

As organizations move to VoIP and other forms of IP communications it is imperative they realize the world of IP is far different from the PSTN and circuit-switched networks of yesterday. While Internet Protocol is the protocol of the Internet which was designed to be resilient enough to withstand a nuclear attack, IP networks need proper management to be able to continue operating under a variety of circumstances.   The concept of the always up IP communications network was certainly in the spotlight recently as TMCnet’s Tom Keating broke the story of Skype, the world’s most popular IP communications software company having a major network outage. He surmised that a recent Microsoft upgrade to its operating systems was responsible for the outage.   A few days later, Skype explained that indeed, Microsoft’s operating system update coupled with a bug in the eBay division’s software was responsible for leaving millions without IP communications.   While some journalists have come to the conclusion that VoIP is no longer reliable because of this outage the reality is that a software bug stopped the network from functioning properly and this had nothing to do with the inherent reliability of VoIP.   Still, when you leverage the benefits of IP communications you must also be aware of the responsibilities that come with the technology. Yes, you now have some responsibilities you may not have been aware of.

IP Communications Education

August 20, 2007

Listen, I don’t want to overdo discussion of ITEXPO in my blog but the fact of the matter is this recent e-mail sent by my marketing team is a great document discussing what is important at the show. It is a good guide for you. What to see, where to go, where to be, etc.   You can see below the various aspects of Internet Telephony Conference & Expo which make it unique and the most imitated event in IP communications.

Skype P2P Problems

August 20, 2007

By now it seems the whole world is aware Skype had major problems last week. For most people, Skype was down. Tom Keating speculated the cause was a Microsoft patch which rebooted massive numbers of machines. He has a point as my machine coincidentally rebooted just before the Skype problem hit.   Many people thought Tom was incorrect but it turns out Tom nailed the problem.   Phil Wolf has an excellent recap of the problem with his thoughts and questions interlaced within.   For example, when commenting on the following from Skype:  
Normally Skype’s peer-to-peer network has an inbuilt ability to self-heal, however, this event revealed a previously unseen software bug within the network resource allocation algorithm which prevented the self-healing function from working quickly.
  Wolf wonders:  
If the bug was within the algorithm, in the Skype client, was the bug ever repaired?

Skype Working

August 19, 2007

It seems Skype is indeed up and running once again. As you may recall, TMCnet’s Tom Keating broke the news of the outage last week when he heard many of the TMC team members were not able to communicate with one another.   I recently wrote about Skype stabilizing two days ago. It seems now the software/service has gone from stabilizing to working correctly.   This is an e-mail I received yesterday from Skype’s PR agency:  
Good Morning,   I'm pleased to share the most recent information on the Skype outage with you:   "Take a deep breath. Skype is back to normal."   "On Monday, we’ll provide a more detailed explanation of what happened.

As you may recall, Voxbone had announced a developer contest a while back and in my blog post about the contest I mentioned the three winners will get:  
  • Recognition as a Voxbone certified developer. Recommendation to customers and partners in need of a third-party developer for integrating the Voxbone API.

TMC Gets Some Press

August 17, 2007

Having your cake and eating it too is how it think about this article in the San Francisco Chronicle with a quote from TMC’s Tom Keating and TMC friend Om Malik. Here is an excerpt:  
Tom Keating, chief technology officer for Internet Telephony Magazine, said he's heard from a number of businesses that rely on Skype to keep workers in touch with each other as well as clients. He said the instant-messaging feature is particularly popular with users because it works around many company firewalls.   Keating said the outage may be related to some maintenance work Skype completed Wednesday night. He said it's unlikely the problem was caused by an outside attack from hackers.   "It's very possible that the change they did with maintenance could have had some unanticipated cascade affect," said Keating.

Skype Update

August 17, 2007

You may recall yesterday that I wrote about Skype having problems. It seems most of the service is back to normal according to Skype’s Heartbeat Blog. Here is the latest blog post:  
As Europe has woken up to a new day and Asia is entering the evening hours, here’s the latest on the sign-on problem.

We’re on the road to recovery.

The State of Telecom Competition

August 15, 2007

The Pittsburgh Post-Gazette has a great story on telecom competition. It is worth a read if you want to understand the plight of CLECs and the industry in general.   Here is an excerpt:  
Greensburg-based Remi Communications, which competes with Verizon in both the Pittsburgh and Philadelphia markets, could end up being charged more to access the delivery lines than it would if it signed up for Verizon's services as a regular customer, said David Malfara, company CEO. "That's above retail rates," he said.

Higher prices would reduce not only competition, but also, possibly, the incentive and money available for improving broadband access.

Telecom Cost Management

August 15, 2007

One of the fastest areas of growth in communications – and there seem to be so many these days, is telecom cost management. In recognition of this fact, TMC has launched a Telecom Cost Management channel which is being sponsored by Optelcon.   Why is telecom cost management an important area? PSTN calls, VoIP calls, FMC, wireless calls, broadband communications, etc have made it challenging to understand phone bills, let alone manage the cost of them.   What sorts of articles might we see on this micro-community? Boy am I glad you asked.   Here is a list of some of the latest content on the site:
