More inexplicable errors?

Five of my algorithms simply stopped trading today. One was submitted to the contest. The other had been live trading for months. None are related to my coding. One of the algorithms literally just reallocates every day at four.

Has anyone else had this happened today?!

One of mine went down today also

This morning we are having issues with some of our servers, which we're working right now to resolve. Users that were running IB real money and paper algorithms were notified immediately, which was a handful of people. If your algorithm is trading in the contest, and it stopped trading today, we will re-simulate the session. Your entry will have a complete history and be back in the contest.

ok awesome. Had the same thing happen, good to see you guys responding quickly.

I am also glad to hear you guys are addressing the problem. Will non-contest quantopian paper trading algos be reset and tested?

Yes, general Quantopian paper trading algos will also be resumed and trading tomorrow.

A little off-topic, but is https://www.quantopian.com/performance supposed to be updating still, or did you guys stop that on purpose?

Simon.

Hi Simon, we didn't intentionally stop updating the performance page. It's a bug in the display logic, and we're working on fixing it.

thanks,
Jean

As a heads up, we're not running a contest leaderboard today since some algorithms were not able to trade. The leaderboard will be run tomorrow evening when all the algos are active.

Simon, https://www.quantopian.com/performance should now be displaying up-to-date data again.
It was an oversight caused by the addition of tracking some data which we are preparing to show soon (tracking larger universe sizes), not an intentional omission.
