We buy burstable 10GE Internet transit and commit on the 95th percentile. We have 2 Geographically separated Network Cores with a 10GE private pipe in between for edge failover scenarios. We have had fibre cuts which with this arrangement we have the capacity we need… no worries…Just a bigger bill in which the provider that failed will pick up the excess in the event of a longer than 4 hour outage as per our agreement.

At what ratio do you decide to buy more provider bandwidth? rule of thumb, because we are all different. With our size, we could probably still afford a 1:1 on the upstream, but we would be wasting a shit ton of cash. Powercode sucks ass for reporting, so its a manual process to see what your ratio is, even though they could pop out report very easily, and I assume query guys already are because Powercode makes it too hard. I am concerned with my personal accountability on this however. Im normally pretty anal about monitoring for points of failure, and I completely dropped the ball on this, relegating some customer complaints to the "quit whining you little bitch" bin, assuming it wa a customer end issue when I should have realized we had sold too much and put it out the small pipe. Any advice (aside from maintaining a 1:1) for metrics to monitor that indicate you oversubscribe? -- If you only see yourself as part of the team but you don't see your team as part of yourself you have already failed as part of the team.
