When someone agrees to post you messages or emails on a certain time or day using a computer or digital device with internet connection however they don't post the messages after making such plans.
Person A: He told me that he'll email me tonight, however I was waiting for his email and messages on facebook but it never showed up. I saw him the next day, only for him to tell me, that he forgot to send the important email. He cyber-stood me up. Didn't he cyber-stood me up?

Person B: He clearly cyber-stood up you on that day.
