Dodgy Office Network

Are the Central IT department telling fibs when they say the reason I have no intranet access is because a JCB cut through a fibre optic cable outside the office?

Some of the servers I'm trying to access are located in the same building as me which makes it sound a bit fishy. What makes it really whiff of rotting tuna is that the internet connection to external sites is fine, including to this blog page.

It sounds more like someone may have messed up a network config. This seems to be what the IT guys have told Cal, who works doing similar things to me for the same company, but in a different building.
