My site was running well for the past three years. Recently googlebot's request my server got increased. and at one time i got network unreachable error. When i contacted my hosting company they asked suggestions from me and i gave a list of google ips to white list. They said that their server will block ip's which are of huge traffic.
After that my site appeared well in google. Now after a month again i get network unreachable. when i inquired them they said i have to change my plan from shared hosting to a vps account or a dedicated hosting.
I have 300 links indexed by google. will that affect much? So i thought of reducing the crawl rate. Please see the image below and give me suggestions.
Previously it was default and now i reduced to the one shown in the picture. Will this affect my indexing in google.
Besides will a server block google ip's for this kind of crawl rate like i have 300 links indexed. and they irresponsible say that i have to switch over to vps. confused.
