Update
The database has been restored from an older backup, which will speed up the time of restoring the data significantly. With this, it's about 90% complete, but still lack about 6 months of data, which will still take about a day to complete.
Don't panik, Nothing is broken!
The frontend of Gridcoinstats is currently replaying from the collected chain data.
Something happened today causing the frontend to revert all processed data to block 0 of the Gridcoin chain.
I suspect some tiny misscalculation in the new way the page detects forks made this happen.
As the page displays more details than the chain can display directly, some processing is needed. This takes some time to process, unfortunately.
Rest assured that nothing is broken, and the chain continues to work as normal.
It's only the block explorer that is affected.
