A quiet day

The Internet is a modern wonder. However if you have to run servers on it, often the biggest wonder is that it works at all. There are so many things that can go wrong with the transport of data from one place to another.

Yesterday, several of the NZ networks were having problems communicating with our server. There was a routing problem in San Diego where packets coming back from the server were routed into oblivion. So the site appeared to be offline. This happened if you were (like I was) on the Orcon, IHug, and probably other networks. Other local networks were feeding in and getting responses from different routes.

I detected it in the morning and informed the hosting company and my ISP by voice message and e-mail. Unfortunately I’ve just started a new job where I’m doing a lot of design work with other people that occupied my full day. So I wasn’t able to have a good look at it until late in the afternoon.

I found my e-mails to the hosting company still sitting in the outbox because the mail server wasn’t able to talk to the hosting company. By resending those e-mails using a g-mail account I was able to contact hosting support who hadn’t been able to detect the problem (my rushed voice message in the morning was a bit short of required information). They started to look for the problem router where the routing table was sending returning packets to oblivion. They also started to work with to give the site an IP that would bypass the affected route.

Meanwhile I’d managed to talk to the server using putty from my iPhone. By doing a traceroute out from the server, and a traceroute from my home system going to the server we managed to pinpoint the router with a problem. The hosting support then organised a reroute around that problem system.

It got implemented last night. So everything should be back online this morning, and I’m able to write you this post. Looking at the traffic from yesterday, it clipped about 30-40% off the usual load of page views. As well as the people who weren’t able to read or comment, some of our authors were unable to put up their posts.

A quiet day, that is unlikely to be repeated today. It looks like the government is providing lots of material for us and you to write about.

    I’m with Slingshot and had no problem connecting to your servers at any time yesterday.

    A traceroute to you this morning records 22 external hops:

    Trace complete.

    For an .org.nz URL this seems a bit excessive.

      The reasons for this have little to do with tech and a lot to do with getting the sites server out of the way of nuisance complaints. This was extensively described in the comments on this post.

      It used to be that we sited offshore partially because of cost and partially because of legal issues. The cost issue has gone away – you can get just as cheap servers here.

      The legal one hasn’t. We don’t trust this government or its wingnut minions not to attempt to shut the dite down with nuisance complaints at a time that is convenient for them. It’d be one of those things that a devious control freak (say McCully) would probably find useful…

      Unfortunately hosting services here will limit their liability by forcing us to remove material or shut the site on receipt of a letter from a lawyer alleging a complaint. The complainant doesn’t have to prove anything – just make a complaint. And who hasn’t got a mate who is a lawyer? So nuisance complaints are cheap and easy to make.

      By siting in the US, we significantly raise the cost of nuisance complaints. You now have to find a lawyer to frame such complaints in the legal framework of the state the server or hosting company is in. So people can’t take us out cheaply.

      Of course if anyone does feel that they have been unfairly criticized by this site, then they are welcome to complain to us. We’re usually pretty good for handling the effects of our inadvertent factual errors on people affected. If they receive no satisfaction then they can take a case to our local courts. But they’d have to prove their complaint and damage to the satisfaction of a court.

      If a local hosting company is willing to give us a contract without one of those drop-out clauses in it, at least requiring some proof of the validity of a claim, we’d be happy to resite back into NZ.

    Thanks for that interesting glimpse of the perils and the active problem solving needed in maintaining the continuance of the blog.

    I don’t understand what you are doing but I value it … thanks for your efforts.

  4. Good job Mr L!
