Backup Connections: Is more ever enough?

September 7th, 2007 · 1 Comment

It was bad enough this morning getting into the office to discover the primary Internet connection being down. This is a 2MB Telewest Megastream leased line which most of the time happily provides the bandwidth necessary to operate our business. Not this morning however, it was down and strangely enough the secondary BT backup circuit - a diverse connection on a 256KB BT Leased Line on an active/passive connection did not kick in either.

I tried manually kicking in the passive connection but it wouldn’t comply. I also tried the backup Firewall unit (which the wide area connections are connected to) and still to no avail. It turns out that the secondary connection was also down. Go Figure.

After a number of support calls involving much “switch it off and on again” scenarios the primary circuit came back online but only after a Telewest swapped out a part “in the field” as the engineer put it - but hey - I was just happy to get the circuit working. However by this time the Internet had been down for over three hours and boy do the users notice that.

The secondary circuit is still down and I’m waiting on the BT engineer to come along and figure out what the problem is. The upshot is that we’re now forced to look at a third connection possibly a simple ADSL connection to at least provide some connectivity when the Internet fails.

The problem however is when is enough enough?
