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:

1. witness server is only 50GB RAM.
2. ZRAM enabled (compressed）
3. 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.

• Delegate to @justyy - at least 5 SP to join (automatically)
• Undelegate to @justyy (Quit) - SP returned by steem blockchain in 5 days
• View Current Delegators/Supporters

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.
