Neiman Marcus Goes Down, But Only For A Special Few

Written by Frank Hayes
February 2nd, 2012

Why are small problems sometimes the biggest pains? Sometimes because they’re the hardest to spot. On January 25, Neiman Marcus’ Web site was inaccessible only to customers using Internet Explorer versions 6 and 8 on Windows 7—everyone else was apparently able to get in without difficulty. This sort-of outage should have been easy to fix, but it lasted more than nine hours.

That suggests the Dallas-based high-end retailer made a change in the wee hours—exactly when you’d expect—but then accidentally left test code in the homepage. The result: a Web site that probably worked fine for everyone in IT, just not for all customers.

The odd outage, which was first reported by Internet Retailer, lasted from 3 AM to past noon on the East Coast. That’s a long time, but walking through it is enlightening. At 2 AM Dallas time, new code went live—but presumably missing IE 6 and 8 from the complicated parsing most Web sites do to optimize each page for whatever Web browser the customer is using.

It wouldn’t have been until maybe 7 AM on the East Coast that any customers would probably have tried the site with one of the browsers that didn’t work. Any of those customers might have called Neiman Marcus’ help line—there’s a link to the number on the site’s homepage. Except of course those customers couldn’t get to the homepage to find the number to tell the retailer it had a problem.

(And most of those who tried another browser probably chalked the problem up to a weird glitch and didn’t bother to call the company.)

It might have been hours before some customer finally noticed and decided to call (or someone at Neiman Marcus Direct spotted the problem). After that, it would have been the usual diagnose, patch, test and go live again. (That’s all an informed guess; Neiman Marcus didn’t respond to our request for enlightenment.)

Ironically, it probably took longer to fix the neimanmarcus.com problem because a well-designed E-Commerce site handles failures like this gracefully. Short of depending on fanatical customers to do your QA for you—or putting up a genuinely alarming error page that exhorts customers to call in the problem—the only practical alternative may be to much more closely monitor error pages after a site has undergone even trivial maintenance.

At least that will give you a heads-up when a whole class of customers goes missing—and you don’t even know it’s happening.

    We’re a relatively small online retailer (12 staff) but we insist our staff check all changes (how ever small) on all the popular browsers. Its something we’d recommend to everyone.

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...
