HI My server provider , recently change my IP, and my page listings have disappear from the serps, I also did a 301 .htaccess for my htpps pages I do not know if this could also be a problem.
i dont think so unless you changed servers and the ip would be from a different country it could effect your geo location like youd rank higher on the search for msn.uk if you had a uk server ip and same for usa.. but in your case i dont see where it would matter.
thanks,do you know what else could have affected my rankings in MSN? , and why my pages are being drop now from the index?
Ip change never affects untill that IP is not blacklisted as suggested by Homebizseo ! How long its been since your IP changed? May be you should wait a little more !
Effects will be temporarily at best, everything should be back to normal within a couple of weeks. However if your new IP address is shared with some spammy websites, it might be a problem.
