There is an issue which does not disrupt the main hosting service
-
Attack ended
The attack ended at 23:28, and went as high as 100Gbit/sec. Scrubbing is still in place.
-
Still ongoing but stable
The attack is still ongoing. The network is stable thanks to scrubbing.
-
Complex scrub through GSL ongoing
Services are still up. Instead of scrubbing only the attacker's traffic, all traffic from all sources is now being routed through Global Secure Layer. This minimises the chances of more nuisance.
Due to the intense and complicated nature of the attack, a so-called 'complex' scrub is currently being done. Such a scrub deeply inspects the traffic, which is the best way to determine which traffic should be let through, and which should be blocked.
In specific cases, such a 'complex' scrub can cause small amounts of legitimate traffic to be blocked. Using semi-random percentages: to have a stable network for 95% of users, 5% of users might be wrongly blocked. Be aware of this if you receive complaints from users/customers.
As long as the situation remains relatively stable, no more updates will be placed for the time being. We will follow up later today.
-
**All** traffic now being scrubbed
All traffic entering our network supplier's network is now being re-routed through the anti-DDoS provider for traffic scrubbing: differentiating legitimate from illegitimate traffic, blocking the latter to avoid the network being overloaded.
Scrubbing could cause some legitimate traffic to be blocked, as there is no 100% foolproof way to differentiate kinds of traffic. The main priority is having the network be stable.
We are monitoring the situation. Services are currently up.
-
Monitoring situation
Services may come back up for a couple of minutes at a time, then temporarily go down again. This is most likely a result of the scrubbing algorithm learning to differentiate legitimate traffic from illegitimate traffic.
We are monitoring the situation.
-
Scrubbing being adjusted
Our network supplier is in the process of adjusting the scrubbing technique with the anti-DDoS provider.
-
Scrubbing started
The DDoS attack's source has been found.
Traffic is currently being scrubbed through an anti-DDoS service. This could mean specific services start to come back up slowly, albeit with latency, but the attack itself is still ongoing.
-
DDoS still ongoing
The DDoS attack is still ongoing. As far as we can currently determine, this attack is NOT targeted at Cyberfusion or one of our customers, but the network as a whole.
Together with our supplier, we are currently investigating the best way to deflect this.
-
Cause found: attack
Our network supplier has mentioned that there was a DoS or DDoS attack going on.
One of the edge routers is currently being rebooted, after which traffic should slightly stabilise. We are currently discussing how long this should take.
-
Network supplier having issues
The issue lies outside our own network - our network supplier is experiencing issues.
We're in contact with them.
-
Network issues
We are seeing network issues since around 19:10 GMT+2. There is a lot of packet loss, which means services are online, but can be very slow.
We're investigating and will report back within 10 minutes.
