advertisement Suffers 3-Hour Crash In The Middle Of Its Labor Day Sale

In the middle of a major Labor Day sale, completely crashed and stayed down for three hours, from about 11 AM to 2 PM (New York time), due to an unspecified network—as opposed to volume—problem, said the chain’s E-Commerce Senior VP.

Although an outage is never a pleasant thing, this one was especially untimely for quite a few reasons. First, it was the middle of the day (or the start of the business day, depending on which coast you’re on). Second, it was in the middle of a major well-publicized sale. And the coup de grâce of this outage: It was a federal holiday, potentially meaning a skeleton crew in the office and perhaps difficulty in obtaining replacement parts.

Site monitoring firm Gomez captured the outage, and it was impressive in its completeness. Typically, outages show a sharp reduction in successful connections and then a performance drop to almost nothing, with just a few consumers able to access the site. The Costco Labor Day crash was a true crash, with the site showing excellent performance before immediately dying.

“During the timeframe we saw on the chart, the site essentially disappeared. The infrastructure itself was simply not reachable,” said Matt Poepsel, VP of performance strategies at Gomez. “We typically see sites slow down as the infrastructure [melts]. This one just fell off the cliff. To see it in the middle of the afternoon is very unusual.”

Ginny Roeglin, who as Costco’s Senior VP for E-Commerce owns the site, didn’t want to get specific about the crash’s cause, other than to say that it was “a network-related issue that required fixing” and that it had nothing to do with traffic volume.

Keynote Systems, another firm that tracks Web traffic, said although the crash was bad, it could have been worse. “This is a pretty extreme event for a major retailer like that,” said Shawn White, the firm’s director of external operations. “Thank goodness it’s not Black Friday.”

White suggested Costco might have benefited from ongoing site monitoring—so it would be alerted to a crash instantly—but there is every indication Costco already knew about the crash instantly.

Why Did Gonzales Hackers Like European Cards So Much Better?

I am still unclear about the core point here-- why higher value of European cards. Supply and demand, yes, makes sense. But the fact that the cards were chip and pin (EMV) should make them less valuable because that demonstrably reduces the ability to use them fraudulently. Did the author mean that the chip and pin cards could be used in a country where EMV is not implemented--the US--and this mis-match make it easier to us them since the issuing banks may not have as robust anti-fraud controls as non-EMV banks because they assumed EMV would do the fraud prevention for them Read more...
Two possible reasons that I can think of and have seen in the past - 1) Cards issued by European banks when used online cross border don't usually support AVS checks. So, when a European card is used with a billing address that's in the US, an ecom merchant wouldn't necessarily know that the shipping zip code doesn't match the billing code. 2) Also, in offline chip countries the card determines whether or not a transaction is approved, not the issuer. In my experience, European issuers haven't developed the same checks on authorization requests as US issuers. So, these cards might be more valuable because they are more likely to get approved.

A smart card slot in terminals doesn't mean there is a reader or that the reader is activated. Then, activated reader or not, the U.S. processors don't have apps certified or ready to load into those terminals to accept and process smart card transactions just yet. Don't get your card(t) before the terminal (horse). Read more...
The marketplace does speak. More fraud capacity translates to higher value for the stolen data. Because nearly 100% of all US transactions are authorized online in real time, we have less fraud regardless of whether the card is Magstripe only or chip and PIn. Hence, $10 prices for US cards vs $25 for the European counterparts. Read more...
@David True. The European cards have both an EMV chip AND a mag stripe. Europeans may generally use the chip for their transactions, but the insecure stripe remains vulnerable to skimming, whether it be from a false front on an ATM or a dishonest waiter with a handheld skimmer. If their stripe is skimmed, the track data can still be cloned and used fraudulently in the United States. If European banks only detect fraud from 9-5 GMT, that might explain why American criminals prefer them over American bank issued cards, who have fraud detection in place 24x7. Read more...
