Why Twitter went down today?

Today(Feb11, 09) Twitter went down in the middle of a busy work day. This outage was for an hr or so...The important thing is that just yesterday there was a news about Twitter planning to charge companies to generate revenue. Then it went down because of an infrastructure issue. How bad is the time...

As I blogged about earlier, the problem is that lot's of these web applications are built on top of 90's client/server infrastructure. Those infrastructure products can only scale on LAN but not on WAN.

This is like driving BMW on a dirt road. It doesn't matter how good is your car, your journey is going to be bad. ..

To answer my question, i don't think this outage is due to Twitter application problem. They are smart guys and know how to build scalable applications. It's because of an infrastructure component which failed them.

Uday,

You make a good point. The Internet is, in practice, a giant WAN. Protocols and systems designed for LAN delivery (they assume certain performance characteristics) are not necessarily appropriate for WAN-like environments - at least not without a lot of help.
