The Economics of Network Downtime
Infonetics Research recently released a study that claims businesses (just in North America alone) lose as much as $100 million a year due to network downtime. Let us dissect that into numbers you and I can relate to.
- On average, businesses suffer from 14 (CA Technologies) to 87 hours (Gartner) of downtime per year.
- A conservative estimate pegs the hourly cost of network downtime at $42,000 (Gartner).
- The cost of unplanned downtime per minute is between $5,600 and $11,000 (Ponemon Institute).
- MTTR (mean time to resolution) per outage, on average, is 200 minutes (ITT Process Institute).
For a quick/rough calculation of your own potential revenue lost, use this equation provided by North American International Systems (NASI).
LOST REVENUE = (GR/TH) x I x H
GR = gross yearly revenue
TH = total yearly business hours
I = percentage impact
H = number of hours of outage
Service costs are rarely zero.
Most businesses associate network downtime with major events or security breaches, but such isn’t always the case. Their own employees could induce it too. For many, that was the case every September. This blog is not about a challenge, but a growth hacking opportunity (transformed from an IT challenge). Read More »

There’s a new force changing the way Cisco IT operates, the way we plan and develop new services, and the way we support our employees. Consumerization is showing us how to help our employees to be more productive and more satisfied – if we can learn to listen and respond. Read More »

With the introduction of Cisco mDNS Service Discovery Gateway in IOS, customers that have implemented the solution are observing client behavior they haven’t seen prior to extending services across subnet boundaries. One of the effects is the duplicate name issue seen when devices with enabled services are moved from one L3 subnet to another L3 subnet and these two subnets happen to be connected to the same router/switch running the Service Discovery Gateway (SDG).
When devices (like a Mac OS X computer) offer a service such as Remote Login (SSH) or Screen Sharing (VNC), they will announce these services using mDNS/Bonjour/Zeroconf using their hostname as configured in ‘System Preferences -> Sharing -> Computer Name’ (see Fig. 1).

If this is the post-PC era, I first encountered computers in the pre-PC era. I remember a field trip to a room of giant kitchen appliances that turned out to be full of information instead of groceries. Despite the lack of snacks, I was enamored with the punch cards they gave us as souvenirs. My dad was amused enough to bring home a whole stack of punch cards from his work — Hewlett-Packard’s Santa Clara manufacturing facility. (Another day he brought home a cat.)
Not long after, I met my first desktop computer when I started learning very basic BASIC programming on a Commodore PET with an external cassette tape drive. Ah, the nostalgia of summer school and CRT displays.
In a recent internet trends presentation to BASE, the Business Association of Stanford Entrepreneurial Students, Mary Meeker, general partner at Kleiner Perkins Caufield & Byers, went through the charts and graphs showing the state of the union in the world of operating systems. In the late-1970s and early-1980s, the operating system world was a colorful place (especially when graphed). Then came Intel-based PCs. Microsoft started to take over, quickly flooding the universe with MS-DOS, then Windows.
Apple managed to maintain a Macintosh beachhead, but it was definitely a sea of PC.
For the most part, it was much like Henry Ford’s infamous “Any customer can have a car painted any colour that he wants so long as it is black.” At most companies it was the same story, you can select any of 14 options, but they’re all PCs. Want a Macintosh? Provide business justification and get VP approval. Today at Cisco, the PC vs. Mac choice comes down to personal preference.
In 1998, Oracle introduced “the concept of hosted applications to the Oracle market, allowing customers to rent access to software hosted on Oracle computers and access those systems via a Web browser.” As eager as Larry Ellison might have been to displace the dreaded Microsoft and PCs with lightweight terminals, the rest of the planet wasn’t quite there yet. Hosted software? Internet storage? Thin clients? Web access? Huh, sounds a lot like cloud.
Fast forward and today we’re in the post-PC era.
Android and Apple iOS have made even quicker, more vigorous operating system inroads than DOS did, thanks in large part to devices and applications.
Smartphones and tablets have outplaced desktop and notebook PCs in global unit shipments since the fourth quarter of 2010, according to Morgan Stanley Research data.
PC manufacturers need to adjust more quickly than most seem to be doing to survive. Says ZDNet’s Jason Perlow, “To put it bluntly, the Post-PC world represents a displacement of computing from the traditional, 30 year-old Intel architecture used on desktop to the Datacenter and the Cloud.” We no longer need the same processing power and storage for the things we do on a daily basis. We have web applications, we have clouds, we have mobile devices.
Today is about mobility, smartphones, tablets, and clouds — ideas impossible to picture on my first field trip to HP. Operating systems, bits, bytes, and cumulus accumulations of data aside, the biggest difference is in how we use our devices of choice today. Emphasis on choice.
“Within ten years, the majority of business professionals will be using extremely inexpensive thin notebooks, tablets and thin clients (sub $500) which will utilize any number of software technologies that run within the browser or will use next-generation Web-based APIs and Web Services … to provide line-of-business application functionality.”–Jason Perlow
