Netflix is scrambling to find answers over delays and outages. According to the company it is hoping to bring its systems online overnight. These issues will come with a price and cost Netflix roughly $1.8 million to $3.6 million in revenue a day, according to Citi analyst Tony Wible.

On Thursday, Netflix continued to “to experience significant shipping issues.”

We were able to ship some DVDs from about half of our distribution centers yesterday but we haven’t yet been able to resume shipping this morning. Our engineers continue to work around the clock to restore normal operations. In the meantime, we’re notifying affected customers via personal email and we’ve posted a notice on the Netflix Web site. We’re as frustrated about this as you are and we once again apologize for the inconvenience.

Longer term, its unclear what impact this will have on the Netflix brand. I suppose that Netflix’s problems could be a win for Blockbuster, but it’s far too early to make that assessment.

Netflix runs on proprietary custom-inventory and customer tracking software.

Netflix spokesman Steve Swasey said the company doesn’t “talk that much” about the company’s internal systems. But he did acknowledge that Netflix’s back-end systems are mostly home grown. “We developed a lot ourselves,” he said.
