After almost 24hrs of trial and error testing spending abt 2-3hrs on phone with my hosting service I have no doubt jetpack is cause of my problems where I can/could barely log into my site getting server connect errors of all types etc. Not sure what was done in the last update but it created massive problems for me.
My apologies if this post is in the wrong place but wanted to let developers know the plugin has a bug somewhere in it that is causing site to redline/maxout CPU and memory usage. Moment I disable it via CPanel file mgr, bc I cannot even login to my WP dashboard to disable via plugins page, everything calmed down.
