This is a reminder that, as announced a week ago, our biannual major system maintenance will occur on October 21, 2021. This maintenance has typically been performed around Thanksgiving every other year, with the last time being May 15, 2020. This maintenance follows up on the WAMP server and live data upgrades, which increased live data capacity from 2 to 20 cores and which were completed successfully last week.
The goals for this maintenance are the following:
- Comcast will be reconfiguring its upstream routers and replacing equipment so that our Enterprise Dedicated Internet (EDI) connection will be eight times faster - 2Gbps symmetric, up from the current 500Mbps.
- We will upgrade from PostgreSQL 13 to 14.
- We will increase the number of mining servers from 9 to 17.
- Chris will modify the configuration of virtual machines to use memory closer to the processors, increasing CPU performance by 10%.
- Chris will reboot several servers that have critical operating system security updates pending a reboot.
We expect the downtime to begin around 11:00am EDT. All services will be offline for the initial period, and then come online one by one, with mining being the last to return. Since we have never had an ISP perform an upgrade like this before, we can't provide an estimate on how long the downtime will be.
