Public Service Announcement: Call Before You Dig (or “10 Most Bizarre and Annoying Causes of Fiber Cuts”)

At Cisco, we strive to provide the utmost in reliability and are particularly pleased with the market leading reliability we have with our IOS XR operating system on our ASR 9000 system and CRS routers.  Whether it’s video, mobility, broadband or voice, reliability is key for a good experience.  However, while we, at Cisco enable the experience, providers are the ones who deliver it – and in doing so, there are huge number of network heroes and heroines to make it happen. When it comes to fiber optic cable, someone somewhere actually has to go out and dig the trenches or hang the fibers, regardless of weather, critters, or angry land owners. This week on Lightreading.com, we saw an article worth sharing from our friends over at Level 3 Communications, “The 10 Most Bizarre and Annoying Causes of Fiber Cuts.
For those of you without the time to check it out (with photos) they can be summarized as:

  1. Construction
  2. Squirrels
  3. Weather
  4. Vehicles
  5. Electrical cables too close
  6. Vandalism, including target practice
  7. Airplane crash
  8. Ice storms
  9. Sharks in the trench (go read it)
  10. Angry landowner with a 12 gauge shotgun

Although I’d expected to read about problems with the weather and construction projects gone wrong, I hadn’t expected shotguns and copper thieves to be such a source of problems, since as we all know  that fiber doesn’t contain any copper (right!?!).

In any case a thank you to Level 3 Communications for sharing their challenges to keep the fiber lit for all of us and sincere thanks to all who help make our network experiences good ones!
