Chainradar's Boolberry block explorer and info has been down since the beginning of October. I've been attempting to contact them about this to no avail (through their contact form).
Anyone else know how to reach those guys?
The reason this is important is because several services use Chainradar as a source for what the block height is, as well as how many Boolberry there are in existence.
Minergate is aware that there is a problem, but has yet to fix it. I contacted them and they are having their dev team look at it
It is interesting that minergate and chainradar both stopped at the exact same tx:
Height Timestamp (UTC) Size Transactions Hash
623703 2016-10-06 10:38:11 (2 months ago)
Chainradar doesn't seem to respond via email.
