Re: Export time out reached
i hope your ISP is working again for you.
With large sites, I usually Export website... / supersite... locally to see if my computer is up to it as a first stage.
I also use Filezilla as I get a better understanding of the server's condition.
Finally, I then try a full Publish and then make immediately a small change and go for a Fast Publish thereafter.
I know I is a bit retentive but I also save copies of the export and the design file to DropBox and USB sticks to save grief later on.
