Have you ever thought about your website value? There are sites out there interent. One I found today iscalled $stimator.com. Not sure it is really acurate or not. But it makes me happy with output of calculating one of my web blogs.
Here is output of cisconet.com's value below
Doesn't matter how much the result is realistic or accurate, it is just interesting to see the value.

The site provides nothing but BGP information. Thinking about hiring consultant? It won't be cheap. The site also provides dynamips files that allow you to play and simulate BGP scenarios before applying production network.

Backdoor only makes the IGP learned route the preferred route. To specify a backdoor route to a BGP border router that will provide better information about the network, use the network backdoor router configuration command. To remove an address from the list, use the no form of this command.

Here is handy BGP troubleshooting tip you might interesting.
I spoke to one of my customer.... He said he had changed BGP configuration last night. He wanted to make other ISP link as the best path, so he prepanding his AS 7 times(wow! that's a lot) on his secondary link. But traffic is still going thru secondary link. why?
He thought BGP will update new changes in sometime soon. He didn't reset BGP session, b/c he was scare to see BGP would bouncing.
I guess he didn't know the command "Clear IP BGP [Neighbor IP] Soft out".
Also, he was not aware that existing route which is being announced won't be trigged BGP update. See example below.

BGP(Border Gateway Protocol) is a global routing protocol which is commonly used between domains, well-known example is Internet. BGP troubleshooting is one of hassel for network administrator. Not only difficulty level, but also hard to collect information of output. Especially BGP with ISP links. You can open a ticket and ask some information, but they won't give you details due to confidential information(?). You can use public routeservers or looking glass, but it doesn't give you what has been changed on Internet. If your BGP link to ISP is fine, but you got below complaints from users
What was going on??? Calling ISP, but most of time they pinpoint customer side or other side user(destination). I discovered this tool few years ago, and I used this tool, iBGPlay, for global BGP route path reviewing.
