This is the error I sometimes get when I try to go a website using an IP address instead of its proper domain name:
Fastly error: unknown domain: 151.101.84.81. Please check that this domain has been added to a service.
I've been wondering as to what the expression fastly error really means? I've heard that fastly is not even a word in the English language, nevertheless it is obviously used by people who speak English as evident from my example. So, what are your thoughts?

As we can see from its -ly ending, fastly is an adverb (if it weren't a proper name). Error is a noun. Adverbs do not modify nouns, and so "fastly error" would be ungrammatical.
The namers of the company may have thought themselves clever, but their error message makes no sense to anyone who is not familiar with the company. The error itself seems an error.
