We have temporarily redirected traffic to our secondary provider while we resolve the issue with our primary network. Updates will follow as available. If you are unable to access your server, please open a support ticket, and we will assist you promptly.

There is a major outage ongoing of our entire network. We will provide updates as available. There is no ETR at this time.

The following shall aid to provide a sufficient overview of the current situation and the work done by Master IT Support.

What happened?

Our network, that being multiple customers at the same time, was within the target scope of a major scale DDoS attack connected to the Aisuru botnet. We faced a total of 5 different attack vectors, each seen in different scale over time and reaching up to many Terabits per Second.
While the actual total peak size is not known, we estimate it to be at around 10-20 Tbit/s peak for one of those vectors.
Certain vectors unfortunately impacted several customers in varying locations, in multiple ways, resulting in frequent degraded service quality for ~60 seconds each.

This attack landscape is challenging for almost all networks targeted by this, as well due to the sole origin of malicious traffic being primarily from residential sources all around the world, with the U.S. being the most prominent source of origin.

When was impact noticed?

The primary impact started at 2025-10-24 21:52:40 CEST and issues occurred frequently until 2025-10-24 23:52:50 CEST. A second primary impact was noticed at 2025-10-25 20:58:42 CEST with no frequent recurrance seen.
Isolated customer impact was bespoken with those impacted and minimized wherever possible and sufficient information given.

We are working hard to address and minimize impact globally and have achieved success in doing so with the majority of vectors, with however one vector stil challenging parts of our infrastructure.

Main pain points are certain path's congesting during said attacks while overall capacity is handled in a proper manner. We are in close communication with CDN77 engineers to optimize this and are working to gain further insights resulting in accurracy while pinpointing impact paths.

Along with that, we have also made further progress on offloading implementations of ddos mitigation algorithms to ASICs, the way, speed and accurracy of safeguard systems acting as well as traffic steering and congestion control globally.
We are also in talks with multiple potential upstream providers as well with different lead times in terms of implementation to evaluate standing as we are.

Our main goal at Master IT Support was and has always been to provide technological excellence, optimal approaches to problems and a generally better and easier protection outcome for each and every user. The issues here however do not relate to technological capabilities of our software and/or hardware implementations, but solely the scale of operation.

We apologize for the impact these incidents caused and appreciate your understanding that we are working hard towards resolvement.
Our customer support and engineering appreciates impact details if any are or were noticed and specifically in regards to geographical scope, destination IP impacted and similar useful information.
Thank you in advance for your cooperation in aiding to resolve this matter quicker.

We are investigating this issue since 2025-10-24 21:52:40 CEST. We will provide updates here as we have more information to share.

The issue occurs frequently for ~60 seconds each.
Our team is working hard to find alternate solutions to address this asap and wants to thank you for your understanding and patience in the meantime.
