I'm not sure if our download machine got IP-banned at your firewall. The appearance of unnamed files in the Ancillary/Meterological indexes broke our downloader, which cheerfully continued trying (and failing) to download these files. We now can't connect from that machine or any others on the subnet, I'm suspicious we got banned for too many failures. The IP is xx.xxx.xx.xx, could you take a look please?
Your IP was indeed blocked. The block has been removed. Take care not to preform the same action that caused the block in order to prevent this issue from reoccurring.
