It is a lot, but only too much if you have issues with it :-)
Problem could be that if you load project with a service which is no longer available, QGIS will try (maybe even 'block') for 5 minutes before telling you 'something is wrong'... So set it to a minute or two unless that is an issue for yourself (I had wfs servers which sometimes took 1,5 minute to prepare my result....)..

Sorry, correction. I actually have my timeout set to 300,000 ms (5 minutes). Is that too much?

When I try on another PC there's no issue and all layers load first time without a hitch! I've also tried adjusting my timeout for network requests to 30 seconds (30000ms), but that doesn't help. Might be a problem I have to put up with, but it's really frustrating. I wonder if there is a way of refreshing my IP whenever it gets too difficult to load these layers!!?
