Dear All,

I have such download errors repeating reproducibly for several days now.

Here is one the the WU's which could not be downloaded:

one more:

And a whole list of them here:

I suspect this should be a server side error?

Cheers,
Igor

Can any of the BOINC experts

Can any of the BOINC experts here shed light on how the download mechanism in BOINC works wrt the different mirror sites? How does the client pick a mirror, and why isn't it trying an alternative mirror when one fails? Bug or feature?

I had to check into that.

Message 78974 in response to message 78973

I had to check into that. Here's what the integrated mirroring should do:

It checks the mirror closest to the time zone of the client. If it can't find that mirror, it should automatically try another in the list, also closest to the time zone. And so further until all mirrors are done.

It is possible that some tasks just aren't there, not on the master server and not on the mirrors. In that case there's nothing BOINC can do. But if the task is available at other servers and can be downloaded by hand, then it would seem that the mirror switching mechanism isn't working.

The question to ask is which BOINC versions are affected?

Hi! While there have been

Hi!

While there have been reports of some files which indeed seem to be absent from all mirrors by accident, there are other reports where changing the timezone of the PC seems to have fixed a download problem, which to me seems to indicate the alternative-mirror-fallback mechanism is indeed broken:

here the file in question is the 4.26 Win App executable, which must be downloadable from somewhere :-).

Apparently it's broken.

Apparently it's broken. ;-)

I emailed David Anderson about it, he asked me to put it into Trac. Done that: [trac]#556[/trac]
