Real life Examples
Ongoing denial-of-service attack 1 year ago
We are defending against a denial-of-service attack, and will update status again shortly.
Update: the site is back up, but we are continuing to defend against and recover from this
attack.
Update (9:46a): As we recover, users will experience some longer load times and slowness.
This includes timeouts to API clients. We’re working to get back to 100% as quickly as we
can.
Update (4:14p): Site latency has continued to improve, however some web requests
continue to fail. This means that some people may be unable to post or follow from the website.
