The difference between 99.9% and 99.99% uptime isn't just a decimal—it’s nearly 9 HOURS of annual downtime vs just 52 MINUTES.
Don't fall for the cloud "SLA Credit" scam, where providers refund $50 while you lose $25,000 during a shared hypervisor outage.
Our iRexta SRE guide covers:
✅ Error Budget math
✅ Defeating the Bathtub Curve
✅ RTO/RPO metrics
✅ Security as Uptime🔗 https://www.irexta.com/blogs/what-99-9-vs-99-99-uptime-really-means/

🔁 Remember the AWS US-EAST-1 outage (Oct 2025)?
A DNS failure in DynamoDB caused cascading issues across 140+ AWS services, impacting platforms worldwide.
No attack. Just cloud concentration risk.

Do we need to mention that Coocook.org was NOT affected by the #AWSdown #USEast1 disaster? 😜
Instead, to be honest, it’s running on a 10+ year old 1U server at a community-organized ISP in my hometown #Leipzig without any complex #HighAvailability setup. The machine has been running like this surprisingly steady all those years 🙈

For this week's #hamchallenge : My primary logging software is #Wavelog. The webserver and backend database both run on virtualized machines in a #HighAvailability #Proxmox #cluster (same one that hosts this instance!). Those are backed up daily to another machine on site via PBS, then those backups are synced to a remote server running in a house in another city.
In addition, my log is also synced to both #QRZ and #LOTW every 6 hours or so, but I didn't think it qualifies as a true backup, since there is some data which those logs don't record.

There, now the services are on #MetalLB IPs, and the #ReverseProxy forwards rukii.net to those. Works perfectly, #ZeroDowntime.
Now everything else is #HighAvailability, except the persistent volumes. For #OpenEBS I'll need a third cluster node, which is in the mail... And of course the reverse proxy and the internet connections aren't redundant yet, in principle I could set up another internet connection e.g. over 4G, but for now the fiber and the proxy are reliable enough.
