Backlinks dropped 70 to 0 overnight??

[Dave0011]

Has anyone had this happen to them? I lost 70 backlinks over night? I am still in the search engine, same placement but no backlinks? I don't understand how this happened or what impact it will be having on my site. Also similar pages has gone to 0 as well. Any ideas or suggestions would be greatly appreciated.

Well it turns out that I wasn't the only one hit with this but nothing to worry about with my site. Apparently google has yet again changed the algo and they have recently started dumping their cache due to people abusing blog links and they are re-indexing sites. So good luck to everyone.
