Clicksor site slowing down my site?

For somereason Clicksors ads have been slowing down my site greatly, the page would load all the way to where ads are and take a long time to load the ads then the rest of the page would appear, it seems it causes the site to hang.

Anyone know how to fix this or is this just a sideeffect of the server issues they are having?

(When I remove ads forum functions normally).

 

Apparently they are under a DOS attack that is killing their system.

It's screwing my sites as well.

here is another thread on it. http://forums.digitalpoint.com/showthread.php?t=958929

 

In my experience Clicksors has a tendency to accept all types of scammy customers. I have gotten trojans and scrips served and stopped using them.

 

It happened to me as well, so I removed their stuff.

 

What do you guys use in replace of them? (Besides adsense)

 

You could try Adbrite... I use them on one of my sites and think they are pretty good.
