I checked to see how much space I have on my Google drive, it's just 100 Gigs. But for $10 a month, I could bump it up to 1 TB. I would gladly to that to help out, but I'm not sure if it would be enough. Are the files being moved same as the channels - 59 gigs or so? A 1 TB cloud drive could work if the files are micro managed while moving.

Just an idea... need to polish a lot to be implemented.

Maybe some of us who use common internet connections could help instead of one, imagine this, each "tape" holds about 50 GB of data, instead of one DL and retransmit all the data back (i imagine 10 - 20 tapes per day) this set could be divided in 10 -20 volunteers and each one do 1 tape at a day. Or even instead of 50 GB tapes use a "small" tape (with less GB on each)
Obviously this is not a permanent solution, and this 10-20 volunteers must be choiced very carefully in the seti community but that could help to pass this complicated days.
I will be happy to help but my internet connection is only 20 MB and not so stable, but if i could help i'm in.
I believe a lot of users will be happy to help.

According to that site, most of Europe, India, Japan, South Korea and Australia are under attack? Sweden, Brazil the Western, Central and Northeast USA, China and Russia are also to a lesser degree?

Who could mount such a massive attack?

Steve Gaber
Oldsmar, FL


North Korea?
Iran?

If you look at the resource from my link, you can scroll back through the calendar year and see where attack vectors originated. Back last year, one of the attack host countries was Zambia. The attacking botnets can be controlled from anywhere. All the various criminal cyber organizations are responsible along with the state sponsored actors like North Korea and Iran and Russia.

An interesting idea. Just the reverse idea of splitting work in distributed computing. I have a 1 TB monthly activity limit on my ISP account. I rarely use more than 250GB any month, so I have spare capacity. But with only a 16/1 MB download/upload DSL connection, getting a data tape sent back to Berkeley will take some time.

But some has even faster connections (not my case 20/2MB) and not see any problem if takes 1 or 2 days to DL/UL one tape since in my idea there are 20 or more others who do the same thing at the same time. If i'm not wrong they use about 10 tapes of 50 GB per day or a little more.
Instead of the lab spend 100$ / TB, that could be another way to help founding the project.
Of course fix the connection problem is the best option. But apparently that is not happening, at least no news on that front in the last days.
Obviously the "retransmiters" must be cherry picked in the community to be sure of the integrity of the data.

Jeff has found an old stash of data that we haven't done yet. He has to do some header fix up (because really old data has incorrect values in the header), and then convert it from 16-bit complex format to 4-bit complex format.

With luck more data should be online tonight or tomorrow.

Yes, good to hear, thanks for the update. I was worried we would be out of data again this weekend before Monday.

And the data being that old would have to mean it's Arecibo, and that means more AP as well as MB. Time spent crunching AP reduces the demand for MB, extending it's time till it's all gone.

I just checked mine and I only have 15 in my account they must've cut back on sizing

If you have Microsoft Office 365 they provide 1 TB of storage. I use very little of it. What is it we would need to do to help out? I have a 50 MB down/10 MB up connection.

Sounds like a job for torrents.
Can the public access Seti at Berkeley and the GBT data through Internet2? If the problem is in between the 2, get a bunch of trusted people with reasonable data allowances and set up a Torrent for each file from GBT. The trusted users download the files from GBT, Seti then downloads those files from those users. Of course this only works if there are plenty of users, and GBT can support their connections, and that Seti's Internet2 connection to those users isn't affected by the data chokepoint.

Take a look at this thread.

Welcome to the 18 Year Club!

You will see there are a few of us that date a bit further back than yourself.
