Daktela Status

Stan aktualny

Zakończone awarie

Drodzy Klienci,

Zaplanowana konserwacja dotyczy naszego centrum danych w Wielkiej Brytanii, więc w żaden sposób nie będzie miała wpływu na klientów spoza Wielkiej Brytanii.

Dear Customers,

Note: this is a preliminary report, the incident is still being investigated.

Partial service outage, June 7, 2021, 10:35 AM – 11:50 AM.

The outage was caused by an attempted DDoS SYN flood attack on Daktela servers. In combination with daily peak traffic, the server buffers became congested and started discarding some packets.

Our systems detected the outage and the Infrastructure Team then got in touch with NOC DT with whom they consulted subsequent steps.

Measures taken:

  • Firewall rules review,
  • Queue router optimization,
  • Deployment of stricter filtering policies.



The situation was rectified when the attack was suppressed and router capacity was freed up.

The Daktela Infrastructure Team is analyzing the incident and working on comprehensive precautionary measures.

We are currently experiencing partial outage of voice and data services. We are investigating the cause, for status update check https://status.daktela.com.

    The services should gradually become operational.

  • 07.06.2021 11:47

    Most services should be now fully functional, we are analyzing the root causes of the outage and consulting the situation with our primary connectivity provider.

Dear Customers,
The reason for the service outages of 1 June was a massive DDoS attack on the infrastructure of our connectivity provider, Dial Telecom a.s.
The attack could be noticed by our customers from 3:30 UTC to 10:25 UTC and resulted in degraded quality of Daktela's voice services.
Dial Telecom has already taken appropriate security measures to eliminate similar attacks.
Thank you for your understanding.
Daktela Team
