My website is 10 years old and always hosted with the same company but now they are just giving me a hard time by not providing good service. I am tempted to switch to a new server from a more reputable company but I am afraid of the disruption in transferring files or with DNS propagation. Has anyone done this? Is this a big risk? I make my living from the website and a disruption will hurt me a lot. Plz help.
