Crack my code

I created an encoded message for my 404 page for my github.io site. Unfortunately I have forgotten what the message is and I can't remember how I encoded it. I'm pretty sure it's not a straight ascii substitution, but I don't think I did anything particularly complicated. Maybe I squashed each character into 7 bits. I can't remember. Can you help me? This is the encoded message:

OK, cracked it:

Error 404: resource not found.
Also, sorry, your personal data has been leaked, but don't worry, we'll post a very heartfelt tweet about it.

Oh dear. I see what I've done. Difficult to automate the decoding.

Nice try but I think the message is longer than that 😁
