Hello,
Last days we have suffered multiple DDOS and ransom attacks and spent most of the time securing our frontend infrastructure.
As we were working on it Bitcoin node failed to synchronize around a few hundred blocks and that's something we have unfortunately missed.
All transactions along with this one have been successfully sent now.
We will probably launch the TOR version today while we upgrade our clearnet DDOS protection.
We will post updates on when our service is live again in this thread as soon as possible.
