My visions for the New Year

OK, if the address is resolving correctly (which you indicate it is), then the issue
is not a cached address or DNS problem, but a router somewhere that is not
handling that address either because it is mis-configured, or it is blocked for
some reason (at least that is my interpretation) since I can get everywhere
else. Hmmm - maybe time to play with traceroute or whatever it is to see just
who is throwing my bits on the floor. (I think your site is one I have never
been able to get to reliably for some reason).

Traceroute gives me these results (my Internet provider is AOL not where the server is) :

If I go to www.traceroute.org and try a number of different sites (especially in the US although I did try several
in the UK), I seem to be getting very consistent non-results -- here is a test from the University of Arizona ...

It is interesting to note the response I got when I tried using "HostingFrance" (www.hostingfrance.com)

Traceroute just sat there although a "Ping" from hostingfrance returned the following:

Just as a guess, since I think it resolves to a china site (.ch ?), it may be
being blocked by people as a source of spam or something -- there has been
a lot of issues like that and I have not been following them.

You might want to do a bit of snooping on the traceroute.org site and see if you can
establish a pattern - it may be time to change ISP's if that many sites have troubles
getting to your web site.

CH is for Confédération Helvétique, which means Switzerland not China !!!
I'll investigate with the server holder as to see why some people can get to this IP
Thank you Mikey for your tries

Oooops !! Sorry about that to all the Swiss people. Something is definitely interfering with
a significant segment of the population getting to your server if the traceroute sites also
can't get there. Good luck !!

Okay, Jeep & Mikey!!!! If I had wanted to be - I would be totally confused!!!!! You're both right, something is wrong!!! I'm in Oklahoma, Mikey is California, Brian (I think it was Brian) is in Iowa and Jeep is in France, so something is wrong somewhere!!! However, enough said, I'm sure you techies will figure it out. Meanwhile, there is certainly nothing wrong w/Jeep's slideshows - they're great! Jeep, I still want the template from "visions re 2008," so I'll keep trying to download it!!!!

Well, that was the point -- "traceroute" is a unix (mostly) utility that will show you the route a
"packet" takes from point "a" to point "b" and when I ran it from a number of locations in the US
as well as some outside of the US, they all got "lost" part way to that IP address. Traceroute
is a utility that allows you to say "hello" to someone somewhere else in the world and it will tell
you all the intermediate sites it went through to get there (and which one it got lost at). Many
people don't realize that when they connect from their desktop computer in the living room to
some place in downtown Podunk, it is not a straight connection - the "packets" of information
have to go through multiple "routers" that each pass it on to the next one in the sequence.
Usually, it works quite well ... what we are seeing here is where it doesn't work so well

(there are often 10-20 "hops" between your computer and the destination). It is, as they
say "transparent to the user" which means either you don't see the middle at all and it works
great OR, you can't see what the problem is at all :shock:

GOOD GOD ETHEL!! (from On Golden Pond)

Well, whatever it is, it is ticking me off. Now that I can't get to Jeep's site, of course I want to even more. Hmmm, how old am I???

I did a bunch of stuff that, of course, I didn't know what I was doing and, of course, none of it worked...so Mikey and Jeep we are counting on you guys - or someone else with this kind of "brain" to figure out what the heck is going on!!

I've never used 'traceroute' before, but I have just had a go from some UK addresses and they did not resolve to J-P IP. They all hung up at, green-ch-ag.demarc.cogentco.com (130.117.243.174) just like you.

However I can still get through to Jean-Pierre's web site no problem. My problem is my schoolboy French from 55 years ago :oops:

by **gpsmikey** » Sun Mar 02, 2008 1:43 pm

Yes, Traceroute does not guarantee the path, but it is often helpful in troubleshooting.
In this case, there are two major possible problems - the first being the DNS side of
it resolving the IP address (which is the real address of where you are trying to get to -
think of the DNS servers as a giant phonebook - you can't simply dial "George" on
your phone - you have to look up his number (IP address in this case)). That was
why I started with making sure that his site was resolving to the correct address - that
takes that side of the equation out of it. Since traceroute (as far as I know) uses basically
"ping" to find the next site, if the next site has the ICMP_ECHO disabled, then ping fails
although other traffic may go through. This means traceroute may fail in following the
path even if a request for port 80 (http) can get through. All that mumbo jumbo
aside, the bottom line is that a number of people from multiple areas find themselves unable
to get to that web site - somewhere in the middle of those "billions and billions of packets"
(to paraphrase Karl Sagen) something along the line is throwing them on the floor
since we know the IP address is valid. Some router somewhere in the system is
sticking it's tongue out at us ... I can just see it now

(8 years ago when I went through the Cisco networking class, the instructor told us that
if we couldn't handle a dozen new acronyms a week, we had no business working with
networks ... he was right !! )

Jeep's site is still not opening for me, anyone that could not open before - are you still having "issues".

I really enjoyed that, wonderful photos. You sure have covered a lot of ground.

Can you tell me how you made the circles flip over please? I think it was in the Bulgarian group.
Thank you again.
Pauline

by **Jeep** » Sat Apr 12, 2008 10:29 pm

Hi Pauline,
Thank you for your interest in my show.
The circles were made applying a vignette effect (ellipse) then I use a zoom from 100% to 0% on one side only to lower them as it they were falling. In fact these are bavarian musicians photos shot in Munich during the beer fair.
