UPDATE
www.wafflepoolmonitor.com :
Due to a bug in code, the graph would jump showing incorrect past values for hashrates and balances, also for some non regular miners on this pool past values would flatline at 0. The bug has been corrected and no such error should be seen now on.
Thanks for the update.
I'm still seeing the problem that I reported earlier where there are spikes between zero and maximum hash rate every 20 minutes. You indicated that this happens when wafflepoolmonitor is not able to get the data through the api from wafflepool for a address.
This seems to happen every day, for hours at a stretch. And in fact it's happening for me now. It started a little less than 5 hours ago.
When I go directly to the wafflepool.com tmp_api URL for my address, I always get back reasonable JSON.
I really like wafflepoolmonitor, but it's hard to get reasonable info out of it when it's in this broken mode.
Because we are maintaining data for more than 1100 addresses, the batch jobs downloading the data fail sometimes. Updated the backend to reduce the failures and not show any more peaks from now on.
I'm seeing some very odd traces from Waffle Pool Monitor:
Any one else seeing similar or is it a problem at my end? I understand the two big up spikes - PW explained this on the previous page but the odd sawtooth display on the left is odd

Thanks
Miles
The sawtooth display on the left is because wafflepoolmonitor.com was not able to download the data through the wafflepool API and not any problem at your end.
This issue has been resolved and such peaks should no longer appear in graphs from now on.
