Only L2 file is there, but L1 file is not. There are quite some cases like this. Is this random or there are just some files in a certain period missing?
Try refreshing your browser.
But last night I could download the following files using curl:
G20161400416 Unable to download file
G20161400516 Unable to download file
G20161400616 Unable to download file

This morning I tried again and I could download them using curl. It appears that this problem is intermittent. I'll see if it continues. Thanks! Chuanmin
