Small businesses that rely on Skype for phone service may be fuming, but should calm down and remember what they paid for it. If you haven't heard, the service is mostly free, with paid features like voicemail for $20 a year.
If you're running a business on free or mostly free services, understand that free never means free. There is always a cost involved. In this case, the real cost of Skype is the uncertainty of having phone service when you want or need it, and the downtime when service is out. To be fair, Skype has heretofore been reliable, and never had an outage of this magnitude.
In other words, quit being sore. You get what you pay for.
