All intermittent SSL connectivity issues, as well as CRC/Corruption issues should be resolved.
If you have a failed download and re-adding them didn't work, mail us the NZB as we'd more than likely need to remove the content from the caches. Please read carefully - re-add the NZB - that does not mean retry the parts that failed. You will need to re-download the entire NZB from scratch to ensure proper data consistency.
The root cause was due to a switch that was misconfigured by our transit provider, where they enabled 9216 bytes MTU settings (Jumbo Frames) on their interfaces without communicating it to us, and we of course rejecting everything over the standard of 1500 bytes.
Our load balancers doesn't give detailed interface statistics, so it was nearly impossible to see that this was the issue, until of course the transit provider
finally provided some of their interface statistics and configurations from their switches
It amazes me everytime how much ass sucking and ball licking is required to get a large telco to simply cut & paste a interface configuration for you - even more so when it's your own interface that you're connected too...
