Bad "Buss Duct" Causes Week-long Closure of 5,000 Employee Federal Complex 124
McGruber (1417641) writes In Atlanta, an electrical problem in a "Buss Duct" has caused the Sam Nunn Atlanta Federal Center to be closed for at least a week. 5,000 federal employees work at the center. While many might view this as another example of The Infrastructure Crisis in the USA, it might actually be another example of mismanagement at the complex's landlord, the General Service Administration (GSA). Probably no one wants to go to work in an Atlanta July without a working A/C.

This is only newsworthy because it was a big building with a single point of failure.
What we all can learn is to avoid single.points of failure in large systems.

No. Bus ducts are installed because of their high current and extremely low maintenance requirements.
Most bus duct systems I've worked on are on 10-20 year inspection regimes, and I have yet to encounter one, even some which are 50+ years old that actually needed maintenance. They are, or at least should be, sealed systems without so much as a spec of dust to cause problems.

For the immediate emergency, no, they didn't.
Long-term, fiber is susceptible to water damage. I had a site that needed fiber replaced because the Christy vault was placed too low in the ground and got inundated with irrigation water. The fiber didn't even splice in the vault; it was just a pull-point where the conduit stubbed up into the vault and a new conduit dropped back down, but the conduits filled up and the fiber degraded fairly quickly despite being gel-filled OSP. For awhile we kept testing and moving to different strands as the ones we were on failed, but it didn't take long before it had to be replaced. Fortunately the contractor was able to eliminate that particular vault entirely, splicing the conduits together after getting the moisture out, and we haven't had a problem since.
