I had multiple problems posting today both from peakd and leo. Also Hive-Engine announced a transaction backlog due to witness issues. They said problem has been resolved but it might take 24 hours for the backlogged transactions to fully process.

Could be a front end issue, but seems to me it is more likely the posting and transaction problems are back end issues.

Also, Ray mentioned today about a posting problem on his front end that lost two hours of work.
