All my sites got graybars including my Hostingcompany

Hi,
Just noticed that all my sites that I run on a virtual hosting account at neureal.com got gray bars. So at first I started wondering what did I do wrong . I added some sites to my account latly and a few i linked to others and worried it might be a bad thing as they have the same ip. I have about 10 sites activly in that account. But 5 are linked together.

But just now I saw that my host neureal.com has a gray bar.

Question is....should I worry about it and take the sites away from them or is it just a small glitch in a datacenter?
Secondly is it or is it not a good thing to link together sites that you own and are on the same ip. They are normal sites advertising services we provide no cookiecutter things and 2 of them are responsible for half of my income.

I'm getting pr on the bar for them, it may have been a connection issue?

 

I noticed the same thing earlier today, if in doubt head to some big sites like google, if they show PR and you get grey on your sites then worry, else its a glitch.

 

I find this happens often, but fortunately they nearly always come back.

 

if it is a ban that has happened to your host and your are on the same ip its likely you have been banned also.

 

I saw some big sites with gray bars so I think it's a glitch.

But am still wondering about the second part of my question. Is it better to have my sites on different ip's if I link them or is it ok.
