Travel Web Site Downtime Problems

Written by Evan Schuman

As the summer vacation season has arrived, travel web sites are getting a serious workout. Perhaps a bit too serious a workout, according to one uptime monitoring service, which reports that one site had 2-and-a-half hours of downtime.

Although the survey looked at 16 major travel sites?including Orbitz, Travelocity, Yahoo and Priceline?Expedia was not among them. Why not? Expedia’s system apparently didn’t take kindly to being watched and blocked the nosey system inquiries from report conductor Pingdom.

“ was originally part of the survey, but the results have been omitted because the service blocked monitoring during part of the test and the results would therefore not be fair,” Pingdom said in a statement.

Pingdom analyst Peter Alguacil said Expedia’s blocking could have been accomplished any one of several ways. “It could have been an automated security feature that was activated after a certain amount of time by too many accumulated visits from our servers,” Alguacil said, “or they could possibly have done it manually?by configuring firewalls, for example. Monitoring is performed from a number of servers, so all they have to do is block those specific servers from accessing their website.”

As for the sites that were tracked, Pingdom considered a site “down” when it either replied with an error or didn’t reply at all within 30 seconds. OneTravel achieved that for 150 minutes and fared the worst. Others included: (94 minutes); Hotwire (85 minutes); StaTravel (66 minutes); Quikbook (34 min.); (11 min.); CheapTickets (six min.); Travelocity (five min.); Orbitz (five min.); TravelZoo (five min.); Hotels (five min.); and SideStep (five min.). The site also tracked Travel, Priceline, Site59 and LastMinuteTravel, all of which were found to have no downtime during the four-week-long test period from May 22 to June 19.

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...
