Our upload server is malfunctioning. The projects are down until we can fix this.

Ah good. Just installed this on my other computer and I have no work available to process. I assume this is the problem. Will wait.

Thanks for the status posting, it helps us to know why we have an outage like this one.

I have been on a data diet for the two weeks, I over did net browsing after thanksgiving holiday. So i shut down seti@home till this last Monday. Now I have twelve reports to upload. today. Any idea how much each upload is or that a variable? I would like to guesstimate what the data flow is, so I can see what I can figure out my data total.

On average, SETI@home workunits are about 8-36KB upload in size, while AstroPulse is only slightly larger than that. And yes, they are kilobytes, not megabytes or gigabytes. They don't consume much bandwidth at all.

PS - I never shut down SETI for browsing the net. Besides the small download and upload sizes, network bandwidth is only consumed during file transfers and not while crunching.

It's about 20-30k per upload. Depends on how many features are detected in the data analysis.

Uploads will be between 20-30 KB and Downloads of new workunits will be 700-720KB.
Downloaded Astropule Workunits might still be 8MB

Uploads sizes can be seen in the transfer tab in Advanced view while they're waiting for a network connection.

Had the thought that the cold here on the frozen tundra had migrated westward enough to cool down the servers and get them going again. :-{)}

We are back. When I've had a chance to catch my breath I'll post a summary of what went wrong. Nothing lost except many hours of my time.

Thanks Eric. Good job.
getting new tasks works.

Sometimes.
Having to hit "Retry pending transfers" 20-50 times to get all allocated WUs to eventually download.

Oh, and is any GBT work being split? Only getting Arecibo at the moment.

Those WU's we get now, was already split and in the "Results ready to send" queue, when things went pear shaped.

Ah.
I had picked up only 1GBT WU out of around 150 downloads, then on the last request I managed to pick up 90% GBT in the next batch of 40 or so WUs

There's not any Arecibo files in the MB splitters now. Not one new MB WU is being split/splat/splut.

Oh...
I can hear the wailing and gnashing of teeth already...

I'll check the GBT splitters. They seem like they should be working.

Most of them look to be working on file blc05_2bit_guppi_57976_02054_HIP73965_0011.

Cheers.

They probably are, just not producing much (less than 30/s, by now it's usually 40+ sustained till the RTS buffer is full again).
Just the usual Scheduler weirdness- got nothing but Arecibo work on my first few requests, now it's nothing but GBT as there's no Arecibo data to split and the Ready-to-send-buffer has been pretty much emptied of Arecibo work.

Web site and forums slow as a month of Sundays or MIA, and no response from the Scheduler for the last few requests, but that's normal for around this time of the day.
MB received-in-the-last-hour & AP Average-turnaround still not updating though.

Is there some stats dumping, or stats downloading going on at this time every day?
As Grant says, this slowdown to a crawl, happens at the same time every day.
Not only are the webpages taking forever to load, but also work requests and reporting becomes almost impossible at this time every day.

And can last from 20min to 50min (usually the latter).

And the splitter output has now dropped to pretty much 0, and the ready-to-send buffer is now 0.
