I am having some issues with my WordPress sites not connecting to outside services. I noticed the problem when akismet stopped working and I started receiving this message on the dashboard :
RSS Error: WP HTTP Error: name lookup timed out
Nothing has changed on the server or the sites but it is affecting all of my WordPress sites on the server.
Also the admin panel is extremely laggy, while the actual site itself runs just fine.
WordPress is up to date and i am unable to re-download using the built in updater.
The issue persists with all plugins disabled.
I have also re-uploaded WordPress core files to no avail.
The host has told me there is nothing causing an issue on the server, but i feel that there may be since it has affected all of my sites.
I am hosted on a vps.
