[sage-support] sagenb appears to be hung
You can get the main page which lists your worksheets, but clicking on a worksheet produces: HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request. --Bill Cavnar -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
[sage-support] sagenb non-responsive and giving proxy error
I logged into sagenb.org a few minutes ago, and brought up the worksheet I've been using recently. I didn't really do anything with it for a few minutes. Finally I came back and tried to evaluate the cell I have most recently been changing. It never responded. Finally I tried logging in again, but now I'm getting Proxy Error messages. --Bill -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
[sage-support] Re: sagenb issues
I have been using sagenb without difficulty now for several days. I've been using it again this morning, but just now I started getting the 'could not connect to www.sagenb.org' message when I tried to save my worksheet. I tried opening another window to sagenb and got the same result. After a couple of minutes, the server finally responded to my first request. I then tried re-running the computation in the last cell that I had been working on. It did run, although very slowly. I have tried a couple of other things, and they were all very slow as well. I don't think it is a connection problem from my end. --Bill Cavnar -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

Thanks! It is back up, although it is still very slow.

[sage-support] sagenb issues
I've been trying to login to sagenb this morning. It took over a minute for the server to respond when I first went to the login page. After another long wait, it finally logged in. Then when I clicked on the link to the worksheet that I wanted, there was a third long wait, which finally produced a 503 error. Now all attempts to reach the server simply produce the 'Service Temporarily Unavailable' message. I know that traffic on sagenb has greatly increased in the last few weeks, so perhaps the poor machine is maxed out in some way. --Bill -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

[sage-support] Re: Downtime for *.sagenb.org
William-- In both Chrome and Firefox, all I got was the 'waiting for www.sagenb.org' kind of indications for more than a minute of waiting. Finally, for Chrome I got the response: Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /. Reason: Error reading from remote server while on my Firefox connection I got the 'Internal Server Error' I got earlier. --Bill Cavnar On Sep 19, 10:27 am, William Stein wrote: > Hi, > > Can people check whether or not *.sagenb.org is working for them.

[sage-support] Re: Downtime for *.sagenb.org
William-- There is still some sort of problem. Off and on all day long I have gotten the message: Internal Server Error An error occurred rendering the requested page. More information is available in the server log. It happens sometimes when I try logging in to http://www.sagenb.org/. Other times I am able to log in, but then within a short time after having successfully logged in, I get the message again while trying to bring up a worksheet, or do something on the worksheet. For a while I thought it had to do with my browser (normally I use Chrome), but then it happened when I logged in with Firefox, too. Here's hoping that that the problem isn't something too hard to fix. I sympathize with you about the disk space issue. It is a chronic problem on another service that I am responsible for. --Bill Cavnar On Sep 18, 10:17 am, William Stein wrote: > Hi, > > I appear to have successfully migrated all the *.sagenb.org servers to > run on a different computer (mod.math.washington.edu).
