As some of you may have heard, Cloudflare is beta testing opportunistic onions. This of course is going to create more Tor traffic. Cloudflare has several concerns about running their own relays and says they won’t at this time. That said if every Cloudflare website becomes an Onion Service overnight how would that affect network stability and what can we as relay operators do to prepare for it?

They use alt-svc but Tor Browser does not support that currently.
I assume opportunistic onions only work for anything that is already on tor.
If I understood Nick correctly they also use single onion services, so that means that their traffic portion is not increasing, just shifting away from exits to non-exits (good).
