Any Given Thursday – Digging into Nasdaq’s 3-Hour Outage

This has been an uncharacteristically bad week for web performance, with several major and historically reliable services reporting outages due to "network issues". In my (not always so humble) opinion:

"Insufficient available bandwidth causing an outage, however, bothers me. A lot. There is absolutely no good reason for insufficient bandwidth to cause an outage. Maybe a slowdown, but if a flood of network traffic (not a flood of traffic to your site, just a whole bunch of traffic on the same network as your site) leads to an outage, something is wrong, at least in my book."

Any Given Monday – Google, Microsoft and Amazon All Experience Outages

It started out like any other Monday morning. I woke up, got dressed, put my contacts in and started making my way to the kitchen for coffee. Along the way, I launched a browser and the mail client on my laptop (as I always do on “home office” days) and I checked to make sure my son was up. After making coffee, I had a few minutes before it was time to drive my 14-year-old to school, I scanned the headlines in my newsfeed.

The top two headlines read:

• Google Outage: Internet Traffic Plunges 40%
• Microsoft apologizes for Outlook, ActiveSync downtime, says error overloaded servers

I only got to read the hover-over teaser paragraphs before:

   a) I realized it was no longer like any other Monday morning and
   b) my son informed me it was time to go.

I am a link to the rest (and best) of this post

Do you have additional insight into, or were you impacted by any of these outages? Comment below.
