Indeed, my approach with SETI outages (as well is the maintenance outages), is to simply suspend SETI processing (there are plenty of other BOINC fish in the sea), until after the wave subsides. With this upload outage, given that it may well run into the Tuesday run, I figure Wednesday evening should be about right.

OK - shortly after my last post hereabouts things started moving again :-P The difference between 0 and 1 is greater than the difference between 1 and 1,000,000 |

I thought Seti had a 100MB bi directional pipe? I haven't seen the uploads go over 20MB. The downloads sit much higher like they should and I know there is some overhead but 80MB? |

We've seen uploads at over 40 Mbps while downloads were over 90 Mbps. IMO it's a duplex 100 Mbps link. The limitation is probably a complex set of things like how fast the server can store the results, how many handshake packets are colliding on the other side of the link, etc. The result files which are at least the majority of traffic on that side are about 1/10 the size of a WU file for MB, 1/500 for AP, so whatever capability the upload server has to handle more than 10 Mbps isn't necessary long term.

The network graphs show there is inbound traffic, but i think most of it is Scheduler requests. For a while there i was able to upload results- eventually. But now nothing is going through- it's all just queuing up again. In the past uploads have been at 30Mb/s sustained. Apart from a couple of peaks at 30Mb/s it's struggling to carry 20Mb/s.
