Witness Back and Upgraded to 20.6 - after 35 hrs offline and Backup Server Enabled!

I started upgrading to 20.6 at Saturday night without a backup server. It took longer than I expected because:

witness server is only 50GB RAM.
ZRAM enabled (compressed）
Main CPU Frequency is only 2100 MHz

I thought witness plugin is the same thing as witness_api thus I removed it and when replay was around 90% - I made another mistake by ./run.sh restart - because I thought it will reload the configuration. Lessons Learned!

It took another 10+ hours because the reindexing had to re-start from beginning.

I thought it would be great to have a backup server in the future because during the offline, I lost three votes.. And most importantly, being a witness means responsibility to produce blocks when needed. We all need to minimize the downtime.

I spent another fortune to rent another VPS - as a backup. Both are now fully synchronized to 20.6 blockchain.

Delegate to @justyy

@justyy runs a automatic delegation service for nearly a year now. Delegate to @justyy for at least 5 SP and start receiving daily payout as interests (from 8% to 10% APR). Also, as a supporter, the delegators will start to receive complimentary/curation upvotes (as a thank you) per day from e.g @justyy and a few other curation trails. For more information, read this. The voting weight algorithm is open source.

Please note that the SP you enter is the final amount to delegate. For example, if you already delegate 10 SP and you want to delegate another 5 SP, you will need to enter 15 SP (instead of 5 SP) in the delegation form.
