No network at work

Today, internet was down from 8.30 to 15.40 (I don’t know the reason). We were able to work on the local network but not further. No mail, no web surfing, no chat, nothing. This gave us the opportunity to work hard 🙂 Soon after the “disaster”, I looked for incidents on verious support websites. I didn’t find anything. But I do find some interesting graphs about the internet connection. For example:
Belnet Liege connection status
Of course, this link is completely useless if the connection is down (since we wouldn’t be able to access it). And, anyway, it’s again a geek-only concern.
