When: Jan 2nd, 2018: 10:07 am
Why: RChain was plugged on CoinMarketCap by Ian Balina - and we received over 18K new visits to the site.
Technical Cause: Still looking into but .. either high burst of traffic triggered event in intrusion mitigation system and a back-off period began or high iowait existed on host due to lack of resources.
Event log
10:07 am: Nash Foster sends telegram notification to Medha Parlikar (Unlicensed) : RChain website down
Info
site: https://www.rchain.coop/
squarespace.com uses a load-balancer or ADC(Application Delivery Controller) (probably NGINX). I would think it caches site in ADC and plays it from memory but maybe not
I can't see any global outages

Mitigation & Avoidance
Never put anything into rchain ecosystem without monitoring from a centralized source of truth.
Coordinate in future press releases to pre-allocate extra resources (automated scaling can take a little time) and have watch performance monitoring closely for fast reaction if their is an issue.
Crypto is hot. Expect a lot of interest in RChain especially in what and how we are going about it.
- We are moving site to our own services to ensure premium service.
- Always cache queries in ram. No spindle disk or even SSD. Use NVME. You can rip Wordpress to static site as well.
