Update 2:
Here's a log from the testnet a few days ago that demonstrates what's happening:
https://slack-files.com/T0YCTJA0L-F5WHTNBV3-b5a795f082
Note how there are connection problems to several of the projects. This happens every once in a while as projects update or change server information or just you know the internet. It's not that big of a deal. Notice how the total synced projects is 37 out of 43. That's pretty low compared to normal (which would be 43 of 43).
Now, with this last superblock, the sync count was 2. This means that only two projects were recognized during this superblock. This means that all the GRC produced by BIONCing is distributed to CPID's(people) associated with those two projects. This is... frustrating, to say the least. GRC was a much smaller community when this happened in the past. As such, development priority was given to larger scale projects -- projects like the recent wallet update and the upcoming unlocking of BOINC team requirments, for example. It would be my guess that this fix might now be moving toward to the top of the list.
As it would be difficult to guarantee 100% connection to all projects at all times, the issue appears to center around how Magnitude is calculated. If Magnitude factored in Magnitudes from previous blocks, the disruption would be drastically minimized, for example. There are several immediate and long term fixes already being discussed. If you'd like to join the conversation head over to one of the many community platforms. I will try to relay updates here to steemit as they become available.
The current situation will most likely be remedied within 48 hours of the last super block created (created 10 hours ago at the time of this update), however until a fix is implemented, recurrence remains a threat.
