DDoS ThreatsApparently the DDoS threat is growing to a point where it is becoming a major concern for data center managers as firewall products’ efficiency is failing.

The security testing organization NSS Labswhich recently discovered that 3 out of 6 firewall devices stop operating when tested for stability.

Are You Looking at the Right Metrics?

Posted on August 17th, 2011 by Victoria Pal in Tech

Performance metricsThe most dangeours type of downtime is the one you don't know about. It is discturbing how true that one line actually is. Should it occur, website/server downtime can and will cause problems and ripples throughout your organization. Before we get tarred and feathered for making such a bold statement, let us build our case.

The Problem

In this realworld situation, a business lost roughly 30% of their leads for July. Apart from their initial loss, they simply handed out a good portion of the market to their competitors, in high season. When the figures arrived, all hell broke loose. All major markets felt the downturn. In search for a logical explanation, hours of daytime were invested in finding the reason. After it was made clear that the traffic was stable, the management went on to search for answers somewhere down the line. The marketing team had to pull out detailed reports for their activities in the last three months. Seasonal sales people got numerous tests calls. A full-scale internal audit took place. This caused a ripple effect and the normal workflow was seriously disrupted.

Custom Error Pages

Posted on March 22nd, 2011 by Victoria Pal in Tech

Custom 404 error pageAs you most probably know, each year we have several seasonal report periods during which we monitor the leaders in the retailing industry to see if their online performance matches their reputation. This year is no different and last month we published the results for this Valentine’s day online retailer monitoring.

One of the interesting cases that caught our attention is the site of Victoria's Secret. While at first glance their uptime does not strike the user with a 100% uptime percentage, the downtime recorded for their transaction happened regularly (every 2 days), always around 5 am and lasted usually for about 15 minutes. Since 5 a.m. is clearly not the busiest shopping time of the day, it was most likely a regular, scheduled site maintenance. However, this was not indicated either in their error message or elsewhere on their site. Instead, next to the picture of the stunningly beautiful Alessandra Ambrosio stood the awkward downtime excuse "We're sorry, our site is temporarily unavailable." .
