I wonder if we are looking at more "HE Problems".

For the last few days downloads have been very slow. We have all been blaming AP's, outage recovery etc. etc.

BUT. Thanks to a suggestion from "Kirdnem(Vince)" I switched to a proxy at around 0930Z on Sunday. Downloads immediately picked up and started to come through at a good rate of knots with very few errors and timeouts. Across my rigs I was able to download approx 3,000 hung MB WU's in under 4 hours.

At around the same time it was reported in the "Panic Mode" thread that downloads had picked up so I switched one rig back to direct to see what was happening. The difference was amazing. Downloads were coming though on the direct path but they were slow, no more than around 2.5kBs and there was still around a 50% failure rate due to "http errors" and "failure to connect()" errors etc..

Through the proxy it was a totally different story, downloads were coming through at speeds of up to 50kBs and averaging 25kBs, errors were down to less than 5%. Also upload speed had doubled compared to the direct path.

The odd thing is that pings and trace routes to the servers didn't look too bad, packet loss was around normal and the ping times were acceptable considering the heavy traffic.

The above was still the case at 1700Z. Computers on the direct path were struggling to get through while those on the proxy were having very little trouble. All computers are connected to my home network and I tried each of my 6 rigs on both paths with the same results all round.

Recently most of the transfers I see are in the sub 5kbps range. However I do randomly see faster ones up to 100kbps. With the bandwidth maxed out things are expected to be slow with 42% chance of rain.

I wonder if it would be possible to set a browser to use the same proxy, and then use a web-based traceroute like net tools to work out the difference between the direct and proxy routes?

You missed the point of my post, through the proxy, download speeds were consistently 10X higher than what they were direct. There was no randomness about it, those results were observed over an 8 hour period, maxxed out Crickets not withstanding.

Yup, same here, tried the proxy at 69.163.96.2:8080, got 40KBps with no problems. Went back to default, at best 2KBps, and then it hangs.

I'll try it in the morning (my time) Richard, it's now 3am here and I need my beauty sleep (as much of it as I can get <rueful grin>)

I understood what you were saying. I was just trying to share what I have seen & adding a note of how screwy things can be while we are maxed out.

I gave a proxy, 69.163.96.2:8080, a try to see if I would get the issue you are observing. However I got the same throughput with both settings in the 30-50k range. Now I'm out of downloads with my limits reached. Granted I had < 10 on each machine.

I have as of now 45K through that proxy, while not able to download anything without the proxy.

Just for the grins, after having all kinds of problems downloading here lately, I tried it too. What an unbelievable difference, and as soon as I went back to default I had the same problems all over again.

Well bugger me.
Just gave the proxy suggested a go. When it doesn't want to download it time outs occur much faster, but when it downloads it's generally a minimum of 30kB/s, had a couple at 100kB/s. Once it starts downloading it doesn't slow down & stop. Makes a change from a download starting at 5-10kB/s, slowing down to 1-2kB/s before eventually timing out.

EDIT- upload speed appears the same, but the last couple of Scheduler requests were considerably faster than they have been.

I've been cut out completely (unable to upload/download anything) since Saturday 5th. None of the proxies suggested here dont seem to work either, got about 200 tasks to upload :(.

Did a traceroute to 208.68.240.13

So it looks like the problem is nyiix.he.net [198.32.160.61], dunno if this is HE server or not...

I do get almost identical results with 208.68.240.16, 208.68.240.18 and 208.68.240.20

I'm pretty sure there are no problems at my end, i've checked everything, same results without firewalls etc. also Einstein@home works perfectly fine.

I got another download and I gave the download servers in the hosts file and using .13 I couldn't download anything and .18 was fine. I don't normally have any issues when this is acting us as my router sorts this out for me.

208.68.240.13 boinc2.ssl.berkeley.edu
208.68.240.18 boinc2.ssl.berkeley.edu

Edit: Also when the router was barfing all over itself before I didn't have any issues on my home connection. My work connection was unable to connect for some time, but it is currently w/o any issues it looks like.

Holy WTFragglemeister???
Just tried the proxy here on a rig that was struggling to download.
Zoom zoom zoom go the kitties.

How is this possible?



I don't know, but it will be interesting when someone figures it out. It managed to clear all 600 of my backed up work units in good time.

And thanks to Kirdnem(Vince) for his suggestion.

That proxy certainly has a good line into the servers.
Recently been struggling to get data through, lots of re-tries, back-offs and all. Try the proxy and ZOOOOMMMMMMM, straight through, no messing, speed 40-60k compared with not a lot.
There's certainly something "not right" just now in the direct path betwixt me in the UK (on Virgin Media) and the S@H servers in Berkeley.

(Just had one go through on the proxy at >100k!!!!!)

Same thing for me here in Northern Arizona, straight connection slow and backing off, proxy is just coming down with no problem.
