DDoS attack

Dear Customer, Dear Partner,

A DDoS attack is ongoing since Wednesday, 12/03/2025, starting at 7:15 AM CET, targeting one of our customer.

IMPACT:

• The service remain operational with a minor impact on the platform’s response time for browser clients.
• However, probes and API clients may have issues contacting the service due to packet loss (without aggressive retries like web browser).

Update (11:00 — Mar 12)

Attack is still ongoing, but at very low rate. Impact should be nearly invisible for every workload.
We may have identified the source of the sporadic traffic loss, related to the attack typology. A fix will be deployed soon to address the issue.

Update (07:20 — Mar 13) ··

Attack ended at 7:15 AM CET on 13/03/2025. Traffic capture have been done both by UBIKA and OVH, various mitigations are studied to be more efficient at reducing the impact of those attacks.
