Java Takes Down the Network

Java Takes Down the Network is a fascinating story about a timed, intermittent network outage.  In this case though I can't believe they still had coax Ethernet cabling.  Well, actually I can.

Jim, who I've mentioned before, stated that when his current office was wired for networking the high school kid run the cable across not one but fluorescent light fixtures.   Worse the cable was right over the ballast.   Jim had been having the occasional network disconnect message but it was a misleading message.

Relevance to Access?   This kind of network problem can easily cause Access corruptions.  When I look at the Corrupt Microsoft Access MDB Causes - Hardware page I stated "If you are running BNC/coax throw it out.  However this highly unlikely these days thankfully."   And I wrote that probably about ten years ago now.

I've personally seen corruption happening in a old house renovated to be office space with an overloaded electrical system.   It was so bad that the server and every work station had a UPS.  I was over visiting and suddenly there was some corruption on a table right there.   I went and looked at the server and saw it had a UPS.  I couldn't find the hub/switch as it was hidden behind a filing cabinet.  I told them it needed a UPS.  The network guy said it didn't.  I insisted back. They purchased a UPS and I never heard from them again.

(That office was so crowded they had two smallish desks in the small bedrooms.  To get past one person sitting at one desk they had to move out of the way.)
