I have similar anecdotal evidence from Norway. A bank outsourced running IT systems to a company from India. A year later they hired a local company to fix/redesign things.
Yep, many people who have been in the industry have heard this one before and/or inherited the project-from-hell that has been touched by half a dozen offshore dev firms and basically needs to be scrapped. There's a reason why we aren't all jobless while other countries take all our tech jobs; it's highly-skilled labor, which means that the quality of the end product is directly influenced by the skill of the workers. The time differences and language / cultural barriers (I forget the name for it, but IIRC there was something in Indian culture around ~"my part is done" which is part of why e.g. There's so much trash in the cities -- basically it's not your problem -- please correct me if I'm misunderstanding or misrepresenting this) certainly don't help set up these situations for success.
