so the faster ur internet is, the less or smaller chance u have getting it?

not necessarily. if there are too many connections to the server, it can't handle all the requests for data. it comes down to how many people are connected at a given time. And the server's ability to handle the requests for data from each connection. The speed of your internet factors in some, but it's not nearly the entire picture in this case. A larger, higher capacity server generally fixes the issue in the long run.

Web servers can only handle X amount of requests concurrently.  If the amount of people hitting the server at the same time is greater than X, an error page is returned and your connection to the server is terminated.  Once the amount of active connections gets below X it will process new requests.  Its also worth noting for those non-techie people that while you are "connected to the forum, i.e. logged in" you do not have an active connection to the server.  An active connection is when you click a link on the site or refresh a page, causing the web server to serve you content. 

Also, if we are using more bandwidth than we should be using (according to the people who own the server, GoDaddy I believe) it is possible that their firewall or router will step in and generate some of the error messages as well, as a way to limit bandwidth. 

So its quite possibly a double edged problem, the server can't handle the load (hitting max connection limit) and we are using too much bandwidth.  The solution to the problem is simple, it just requires some money to implement...

The problems aren't caused on the client side, all the server load and bandwidth issues are entirely on the server side of things.  I still see the errors every now and again, but it really depends on what time you are on the forums...

also weird then..., i haven't had any problems for around 2-3 weeks and before, i've only had minor problems with which i just needed to click refresh, and then it's okay
but it's good, ofcourse i don't want server problems xD

There is one, go look at the main http://learnnavi.org site.  Its at the bottom of the page...

This problem could have been fixed weeks ago when I emailed seabass, but he never got back to me, so yea... dont go hoping on much  ::)

I am sorry you are disappointed in how the forums are being administered, but you should note that fixing the load issue is not as simple as just starting a new server.

Well considering my job involves day to day running of webservers and php scripts, with 95% of those running various databases, with one site that more often than not has 1500+ simultanious users, I would say its a fix that could be sorted in about 30 minutes  ;)

I am sure you are quite competent. If the issue was merely technical, your statement would approach being accurate. In this case, it is not.

That is my last word on the issue.

To help people understand a little better:

An  "Unable to service your request" error means that the max capacity of the server has been exceeded. You need to hit F5 or CTRL + F5 to try again. This is the most common issue people may be running into at the moment. Nothing is wrong really. It's just that the server hit a "traffic jam" and can't service any more requests at the moment. Refreshing usually gets you back on the road in a few seconds.

A "Bandwidth Exceeded" error is just that. The maximum bandwidth for the site has been met. And no further data can be served from the server until the next time bandwidth allocation resets (on a monthly basis in general). Bandwidth generally isn't a problem. Until you start adding pictures and videos. The one reason sites forbid "hot-linking" (directly linking to an image on a site) is because that link uses bandwidth to serve that image to the hotlink. The site pays for that bandwidth. It also reduces the capacity for that site to serve more data from the servers. Bandwidth is generally issued in gigabyte increments. For a text forum like this, 5 gigabytes of bandwidth a month is generally fine. You may think that's not a lot, but think about how many requests for data are made to this forum a day. You may only add a few kilobytes of requests a day during your browsing here, but multiply that by the thousand or so regularly posting members, and also guests and you get a far larger number than you think. We probably won't hit this error a lot. But if we have a period of explosive growth, it would be possible to have this issue come up. I've seen it happen before once or twice. Raising the bandwidth fixes this issue.

Just some insight on forum mechanics relating to the topic at hand. ^.^
See that shadow? It's the last one you're gonna see.
