I am a developer working for a small company. For my own purposes, I have developed a small VS desktop program that allows me to cycle through some favorite web sites through the company's network. The URLs are contained in a database, and a click will move to the next URL or the previous URL. I've had this setup for a couple of years with no problems until now.
Earlier in the week, one of the sites in the rotation was inexplicably and consistently redirected to localHost (127.0.0.1). The next day it was fine.
Today I find that another of the sites in the rotation is redirected to local host. I checked on different browsers and on different machines, and it happens on all of them.
My situation here is that the network administrator has a grudge against me, for whatever reason, other than the fact that he is extremely childish. Not being a network expert, I am wondering if there is a way that this guy could be playing tricks with me by blocking and unblocking the URLs that I frequently go to. And is there a way he knows if they come specifically from my machine?
It needs to be pointed out that these sites are in no way restricted or controversial, i.e., not porn or any other kind of contraband. In the case of the blocked URLs they are standard comics pages that are no different than ones seen on a newspaper page.
How should I address this issue with my employer?
