Can't access the forum normally

[crossmr]

Just a heads up, something happened since last night, I can't access this forum normally here from South Korea. All day I haven't been able to get on, it keeps saying it isn't responding. Finally I got tired of waiting for it to resolve itself (also happening with a couple other websites) and installed Hotspot shield, instantly fixed the problem, however hotspot shield doesn't play nice with imageshack. Anyway. I've done a tracert, and definitely some problem closer to your end than my end. I'm getting out of the country just fine.

Not really sure what is going on. With hotspot shield on, the tracert completes. The couple websites I'm having issues accessing are in very different areas (one in california, bloks forums, and this one) so I can't imagine it is really anything going on here, but odd that 3 websites get knocked out for me all at the same time.

Trace complete.

Just to clarify, was your browser telling you something like, 'Can't access the page http://www.eurobricks.com/ because the server where the page is located isn't responding.'? Because it's been fine for me, so my only guess would be a server problem. I get that sort of message all the time on MOCpages, presumably because of all the traffic heading to that site, and I know the site isn't down, there are just too many people accessing it.

[Big Cam]

If its only happening to you, I don't see how its a forum problem.

[crossmr]

Not necessarily a forum problem, but it is likely a problem with the forum hosting provider. Unfortunately I have no idea who that is, and I'm not their customer so I can't deal with them. but they've obviously either lost their routes back to South Korea somehow or have stopped serving traffic here or to this ISP.

No, that's not how it works. This would be a DNS error; not in any way related to us. Hotspot Shield makes you talk to EB via the US and thus you use different DNS servers.

I wouldn't worry; in most cases DNS errors are fixed in a few days.

Er no, it wasn't DNS. The IP was being resolved fine. I just cut it off the top of the traceroute

Tracing route to eurobricks.com [83.169.34.155]
over a maximum of 30 hops:

I used the same DNS servers for both because I don't use my ISPs DNS servers, I use opendns.

there was a routing issue and I got word back from my ISP that they had worked out some fix, and all the sites that were inaccessible, including this one, seem to be fine now.

...which is much what I said. You said it was "likely a problem with the forum hosting provider" and I said it was not, and made a guess that it was a DNS error. In any case it was a problem with your connection, not ours.

Routing and DNS are two different things. I was a network engineer and a CCNP.

DNS is solely domain name resolution, names to IPs. The IP was resolving fine as I noted and checked at the time. Routing is concerned with how a packet gets from one network to another, and in the case of the internet is handled by BGP. The fact that the traceroute got nearly there and then died tells me that either the hoster or their provider had lost their routes to this ISP or a portion of this ISP. This isn't uncommon and happens from time to time. It is sometimes intentional in the case of route poisoning. Very likely the fix they applied was to re-advertise the route to ensure it got passed all the way along and restored the far server's knowledge of how to get back here. Were it a DNS issue the IP address I'm getting for Eurobricks now would be different then I got then. It is the same, and was the same both through hotspot, and through the second ISP I have access to. The problem wasn't in fact mine or my ISPs, and may have been your providers since you can see the successful traceroute going one hop past what it went to before

before succeeding. Before I was unable to hit car1.dusseldorf1.level3.net server, which is likely who had the routing problem. Anyway, it is solved now and they've had their routes restored.

Yeah, I know. I never said they were the same thing. I was trying to help you, I was in a hurry, and said DNS when if I thought for more than a second I would have said something else.

In any case, I used to be in the RAN working on RADARs. Not relevant I know, but I'm just making a point, and the point is I'm stuggling to see what you're trying to achieve in this dicussion. You say at one point it's us...

Anyway. I've done a tracert, and definitely some problem closer to your end than my end.

...then you say it's not...

Not necessarily a forum problem, but it is likely a problem with the forum hosting provider.

...and then you make this big post saying how good you are. Was that your goal? In any case I won't be jumping in to try to help you in future. As a CCNP you should be able to work things out for yourself.

My ISP applied a fix, but it wasn't to fix something on this end it was to fix a remote server's knowledge of where the network lied, the remote server likely being your hosting provider or their ISP based on the result of the traceroute. They along with a couple other servers lost their way back here.

I was simply trying to make you aware of an issue that was affecting how users interacted with and used this site and that was likely related to something on your end.

I didn't try to bring up my background at all until the "I told you so" tone of your previous post, and actually after writing it and thinking about it I came back here to delete it, but you'd already replied.

Well if I came across as rude I apologize.

As do I, I was just trying to keep you guys informed.
