BacklinkWatch has been shutdown? Really...!!!

Hi there, For competitor's backlink research, I always used backlinkwatch.com which is best from other backlink extractor websites. But, I m watching for 3 days the website has been shut down and I m totally upset. Is backlinkwatch is really shut down for forever? What do you think?
Also, suggest me any free backlink checker tool which I can use for extracting backlinks from competitor's website. Thanks a lot.

its a pretty old site, probably never made money, found no buyers, so they may have decided to shut down and move on cos the pros use semrush and stuff and only broke ass noobs use their site. Not the best set of users to make money out of.

Not working here as well. Looks like they have completely shut it down or may be changing their servers.
