Our computers are placed in a Local Area Network, recently I found a significant reduction in web browsing speed, when I did a tracert google.com encountered with results below:

Is it really normal?

is this at your work and you are responsible for systems administration or is it a private/home issue? –  Lorenzo Von Matterhorn Apr 6 '13 at 10:19
    
@Znau, I'm a computer end user not the administrator –  rev Apr 6 '13 at 10:21

if you have someone responsible for sys/network administration let them know of that tracert; you may be behind a VPN/proxy. if you can handle it accordingly to the company policy, check your proxy settings and place them on direct/no proxy and your hosts file. –  Lorenzo Von Matterhorn Apr 6 '13 at 10:25
    
The number of hops seems reasonable, the latency doesn't. For comparision: edit I tested two traceroutes to google.com from two different computers (from home and from uni). Both show 13 hops and 16 ms until they reach they local google. (local since I am assuming CDN). –  Hennes Apr 6 '13 at 10:55

Asking if this is normal is not really a good question. Normal could be different for lots of different people. For instance - if I traceroute from home, I will have one internal hop (my router) then make it to google.com in 13 hops. However, at work there are more internal hops; which is normal. If you work at an ISP there will probably be very few hops; which will be normal. So a better question would be to let us know of a change that happened that resulted in slow browsing, or give us more information about your network (might be illegal). Alternatively, ask you netadmins! They will know. –  prateek61 Apr 6 '13 at 13:07

It's not wrong. It's not ideal either. It may very well be "normal" for your network. Understanding where the latencies come from and why they are there isn't always easy. This presentation is worth the read. It will give you some idea why you could be getting these results.

Looking at the response times a couple of things are clear. First, The device at hop 6 (217.218.189.186) adds a lot of latency. It is responsible for almost all of the latency between it and hop 19 (66.249.95.132). You can see that many of the response times up to hop 19 are actually less than the values at hop 6. Second, from hop 20 onward the response time starts growing again from hop to hop.

The number of hops seems reasonable, as the other comments state, though it's on the higher side of "normal".
