Service Unavailable on most of the topics

[thndata]

Hi.

I get this error:

Service Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

The thing is that the error occurs when i try to access most of the topics but not all. Some topics shows up as the should.Always the same topic though.

I'm totally clueless over the strange behavior. What can cause this?

Best Regards

Contact your host.

The ones you can see are probably being drawn from your browser's cache.

You need to check all logs & resource charts for clues.   This can sometimes happen when hit by multiple, aggressive crawlers.

Thanks Shawn.

Will crawl trough the logs and see if something odd happens.

Cant spot anything odd though.

But very strange that some will open but not the most. It can't be cached either as the server has been newly recreated. and I have changed the computer some times after the post was made.

So i swapped the server and now it looks better.

However i get this strange redirect thing that redirects to the old server mywwwadress/index.php?wwwRedirect

What is causing this and where to change it so it wont redirect. It might be an issue with the server swap and it only needs some time for the DNS servers to update?

Best regards

Topics a viewable again.

wwwredirect is an SMF function to correct the URL when you enter without www but the setup is done with it, or the other way around. That has nothing to do with servers per say
