Load Balancer Nodes: Improve Success Rates by Checking Jussi Number

The Open Source Steem Load Balancer Nodes: https://github.com/DoctorLai/steem-load-balancer

I have deployed/maintained two:

London, UK: https://api.steemyy.com
Dallas, TX, USA: https://steem.justyy.com

Improve Success Rates by Checking Jussi Number

Previously, the load-balancing algorithm selected the fastest node by sending a get_version request. However, this approach could choose a node that was not yet fully synchronised, as indicated by a jussi_number of 20000000. Then the subsequent forwarded requests may fail.

To address this, the latest updates now verifies the jussi_number and excludes nodes that are significantly behind the latest recorded jussi_number.

See commit

Additionally, rejectUnauthorized has been enabled to ignore SSL certificate errors by default.

Statistics

You can simply send a GET to see the statistics of the load balancer node:
