TechCrunch is reporting that eBay market cap lost $1 billion dollar on August 16 because of Skype outage. The outage started the 16th and lasted for approximately 2 days. The chart shown by TechCrunch looks convincing enough, but let's zoom out for a second (see the chart on the right; click for a larger view). First, eBay stock started going down a few days before the 16th. Second, it went up on the 17th, while the outage was on its second day. So just looking at those charts, it doesn't seen that eBay's stock has been impacted in any significant way because of this issue.
