Several years ago I participated in a conference as a speaker, and my speech was so good it got a third place award for the best speaker.
For many years it was stated on the organizer's website, and I've placed the link to it on my linkedin profile and often used on my CV.
But today I clicked on the link I always used and it was dead. They don't archive conference websites from 8 years ago. So now I have no proof of anything.
Should I continue mentioning that award on my CV (I have a nice story about that), or does the "dead website" sounds like a conman's excuse too much?
