"Website under heavy load" warning
Incident
Report for Coveralls
Resolved
This incident has been resolved.
Monitoring
This was the second wave of the attack we experienced this weekend, broadened and tripled in volume. We implemented a second phase of defense which appear to be working and will continue monitoring for the next hour.
Investigating
We are currently experiencing occasional "Website under heavy load" warnings.
We believe this is the second wave of an attack we experienced this weekend involving an army of scraper bots which we successfully mitigated. We believe the attacker may have gotten around an initial phase of defense.
Separate from a DDoS attack, these are millions of individual requests coming from over 280K different IP addresses across 12 different countries, so our standard DDoS protection (IP quarantine) does not apply.
We are implementing a second phase of defense and will report updates here.
