Hmm, interesting.
Looking at broker metrics from the last couple days: https://snowflake-broker.torproject.net/metrics
There may have been a small drop in client match counts (from ~10,000 to ~9000) but nothing like a total outage.
It looks like there was a drop in bridge users on the 16th but not an obvious drop in the date range of the DDoS attack: https://metrics.torproject.org/userstats-bridge-transport.html?start=2020-12...
Thanks for the heads up. I'll keep an eye on the metrics because it sounds like it's still ongoing?

Greenhost sent an email saying that since last 2020-12-17, there has been a DDoS attack against their infrastructure. This may affect Snowflake, because the broker and bridge are hosted by Greenhost in Amsterdam.
Please bear with us as Greenhost and the eclips.is platform are suffering from some of the largest DDoS attacks we have faced.
Between Thursday and now we have seen targeted attacks on one of our users and directly at Greenhost.
Our upstream provider in Miami has unfortunately completely dropped the eclips.is infrastruccture routing as they could not withstand the attacks. We are working to put that connectivity back up as we speak.
The situation in Amsterdam is more under our control, and both Eclips.is and Greenhost networks are available as of writing.
2020-12-17 09:10 outage caused by a major DDOS attack https://status.greenhost.net/incidents/19
Since 10:10 CET, we have been experiencing outage caused by a major DDOS attack.
All VPSes, webhosting and emailservers were affected by this outage.
We have deflected the attack and worked to recover all systems.
2020-12-20 15:00 Repeated DDoS attacks on our infrastructure https://status.greenhost.net/incidents/20
After the DDoS attack last Thursday we did see recurring attacks of increasing magnitude on our infrastructure. We are working through the weekend with our technical service providers to increase resilience of our network. We will update you as the situation progresses. At this point our services are operational.
