Something is happening to the network connection between Green Bank and Berkeley that is slowing down the rate at which we can transfer data for splitting. We've opened a trouble ticket with campus networking services. Hopefully they will be able to find and fix the problem quickly. Until then, work may be in short supply.

Thanks for the heads up Eric.

This raises an interesting question for me. How long does it normally takes transfer one the tape of data that we see on server status page roughly 52.2 gig will or is more data than that transferred and 52.2 gig is the remaining processable data? Thanks in advance

But except for being both a listening device and also having the capability to transmit as well, also that of a radar being a possible issue here.

Needs checking for the Green Bank here, if not the opposite, but for at least one it should be such a dish, and next also an antennae as well.

https://en.wikipedia.org/wiki/Active_SETI

https://en.wikipedia.org/wiki/Green_Bank_Telescope

Here one possible option, if not any reason for such a thing happening as well.

Leaving that out, always the possible option of making it one thing for another where it also could fit a given purpose for its intended meaning.

It`s just gotta be the soulless minions of the orthodoxy bent on thwarting our efforts to contact help for our planet.
They must mistakenly think their foolish plans can actually effect the actions of our powerful collective.
Slowing our network connection to Green Bank can only serve to strengthen our resolve...plus i don`t really have anything
else to do this week, so ....

. . Hi Eric,

. . Thanks for getting that second Arecibo tape mounted! But is there any hope of more appearing before the outage commences?

Well as it is just past midnight now in Berkeley and the outage usually starts around 5am Pacific Time, I suspect you will have to wait and see. :-)

Matt was able to get us 1.6 TB of data (enough for a day and a half) by first transferring the data to Google storage, then to Berkeley. The problem appears to be somewhere in the internet2 route between Berkeley and Green Bank. We're pushing on campus networking to consider it a real problem (they keep asking if we've checked our cables, even though the problem exists on several machines).

More news tomorrow, we hope.

Thanks for the update. Fingers crossed you can get them to consider it a real problem. I know how that can be, hahaha..

Regarding Arecibo data, we're slow trickling what data there is on the data recorder's mounted drive at 5 Mbps (500 kBps). That's all we're allowed to use because Arecibo only has a 30 Mbps wireless link. Their fiber link was cut in the Hurricane, and there's no estimate of when it will be fixed.

The bad news is we've pulled all the data off that drive, and no ALFA observations are scheduled until Feb 4, so no more Arecibo data until the 5th at the earliest.

I don't know in what format the Green Bank data is stored. If it is on physical drives, couldn't you just overnight them via FedEx? Assuming you have the correct hardware on your end to mount them and get the data into the splitters, wouldn't that keep us going for a few more days until campus networking gets off their Level One script reader response?
