I use WP in several sites under my host Pair Networks -- however every time I use the automatic upgrade for plugins, it takes about 20-30 minutes for that to occur.
I also manage sites hosted for a friend on servers located via theplanet.com, and when we click automatic upgrade for plugins, it happens almost instantly.
I asked my ISP (pair.com), they want to do a traceroute from their server where my files reside to WordPress.org -- but I don't know which server provides the plugin updates for the automatic upgrade feature.
They have advised:
We could check for any potential connection issues by running a traceroute from your server to the WordPress server, but I'd need to know which server it's trying to connect to. It would also be helpful to have a trace going from there to here, which you could get from WordPress support.
Any advice please on how to supply them the relevant information so that this can be done?
