@aaronpk I'm integrating webmentions in my website, using webmentions.io and I might have crashed your server. Although I don't think I ddos-ed it with more than a 1000 requests. Anyway, if it was me, I am so sorry.
It looks like it's still up to me, what error are you getting?
timeouts, but they are gone now. Maybe something network related. Thanks for the quick reply tho!
