It’s not down. There’s a limit on the number of API calls you can make to AvantLink per day. SnapSearcher uses the AvantLink search API so when you hit that limit you won’t get any results. Not to worry! This is a good problem. It means your site is getting a lot of traffic. Just contact the AvantLink team and they are happy to increase your API limits.

I don’t believe so; nothing on their twitter feed (@snapsearcher). ColoradoHiking appears to be searching correctly as well, although I don’t see the code for snapsearcher directly integrated. I’ll follow up with you via email. Thanks!
