Recently, my websites hosted under one hosting account went down for almost three weeks. I had to move to another host, who helped me to get my sites up again.
It had been a painful three weeks, and I was on tenterhooks. It did not help that I was also faced with communication breakdowns off and on, which made things even more difficult.
I am glad that things are a lot better now. Still not perfect, technically, I think, but at least all my sites are live, and I am paying a lot less too!
