VXLAN and Juniper – the quick and dirty way
I made the VXLAN submit to my Juniper whims. I hope this is helpful to others doing a quick and dirty deployment like I was working on.
Denial of service attacks suck
I said it, you read it, hope you aren’t offended. Short summary from my point of view dealing with our denial of service issue this evening.
How do our servers connect?
This morning we had an outage and while I did what I could to describe it via text, I can’t seem to come to grips with three unrelated issues occurring together creating so many pages. Why?
