Okay…it wasn’t the server.
It was Zen, mtu settings, and TCP (?) settings. Not my fault actually, not at all.
But it’s sorted. (what calamity is sitting in the wings next I wonder…)
I have enough stress in my life without everything the last couple of days has thrown at me, I really do. In fact, my stress levels are pretty damn close to being completely maxed out. I have precious little control over those stresses, but when the computer, or the line goes wrong, it just about puts the tin-bloody-lid on it all.
