I run a website, www.seatgeek.com. Today, while visiting my parent's house, I noticed I couldn't access the site while on their internet connection. I got a message saying "Firefox can't establish a connection to the server at www.seatgeek.com.". I checked with several other people using different connections and they could all access the site.
Puzzled, I played around with my parent's internet wiring. I found they had it set up so that the internet was piped from cable modem -> vonage phone box -> wireless router. I swapped the position of the vonage box and the router, and that solved the problem.
If their internet configuration had rendered a number of sites useless, then I would shrug and move on, never worrying about this again. But I find it disconcerting that SeatGeek was the only site that had problems--all other sites worked fine.
Can anyone think of any issues with our site's configuration that might cause this problem? I'm not sure whether the solution (swapping the position of the Vonage box and wirless router) provides any clues...
