Why Twitter kept crashing
By Ria Sharma

Over the last week, Twitter has been flaky.  It suffered from a number of glitches and long downtimes.

Twitter has now blogged about what happened and how they plan to fix the issue on a long term basis

“
What happened?

In brief, we made three mistakes:
- We put two critical, fast-growing, high-bandwith components on the same segment of our internal network.
- Our internal network wasn't appropriately being monitored.
- Our internal network was temporarily misconfigured.

What we're doing to fix it
- We've doubled the capacity of our internal network.
- We're improving the monitoring of our internal network.
- We're rebalancing the traffic on our internal network to redistribute the load.

Twitter has also warned its hundred million plus user base that the traffic during the World Cup could cause problems on some days.
