PayPal Hit By Outage

PayPalsuffered an "internal network hardware issue" that caused a world-wide system outage yesterday. Millions of customers were unable to complete their transactions.

According to PayPal, problem began around 1330 EDT, and affected all PayPal customers for about an hour. By 1830, service was restored to all customers, PayPal said.

It went on to say,

"We’re now working to fully understand how we can prevent such a service interruption from ever happening again. We’re also reaching out to merchants to discuss the impact this interruption had on their businesses."

News reports say that PayPal transacts about $2,000 in commerce per second, so an hour outage is not inexpensive.

In 2004, PayPal had a five day outage due to a software update that misfired.

PayPal is owned by eBay, which has had problems of its own recently.

You’d expectthe longest and most costly phase in the lifecycle of a software product to be the initial development of the system, when all those great features are first imagined and then created. In fact, the hardest part comes later, during the maintenance phase. That’s when programmers pay the price for the shortcuts they took during development.

So why did they take shortcuts? Maybe they didn’t realize that they were cutting any corners. Only when their code was deployed and exercised by a lot of users did its hidden flaws come to light. And maybe the developers were rushed. Time-to-market pressures would almost guarantee that their software will contain more bugs than it would otherwise.
