Blockchain.info's blockcount API call giving error, alternatives? This URL today: https://blockchain.info/q/getblockcount

Was giving the error "Too many requests".

Any alternative out there to get the blockcount via an API? Thanks
Another public API I found for this:

https://blockexplorer.com/api/status?q=getBlockCount

But the best one so far, is blockR.io because it even has testnet support:
