wordpress.com down due to STP (spanning tree protocol) ?

The STP is a wonderful protocol which is required in the first placed to have faster and shortest path resolution when some of the routes to the server are down.And wordpress is down just because of that…..things can go wrong just anywhere.From the post, think the problem is that the redundant port is of less capacity than the original one.May be someone thought it may be never used.Lesson learnt!

There are some wonderful mathematical algorithms like OSPF, RGP which does this work very efficiently using what is called the weights of the links. The topology of the network  changes when a new router is added in the route or a router is down in a particular path.All these happen based on the information povided by what are called BPDU’s (Bridged protocol units ).For more on this try google…its vast and wonderful..
