Please contact our technical support team now.

Why did I receive this notification?

This is why we have informed you:

Technical anomalies have been detected on your connection which may indicate a fault or a recurring quality issue. 

Not every anomaly leads directly to a failure. 

However, early detection helps to identify any potential difficulties in good time and to find a solution together.

What this might mean:

You may not have noticed these irregularities yet, or you may have noticed something but not yet arranged for a further investigation.

  • Brief interruptions to the connection
  • Unstable connection quality
  • Restrictions on internet or telephone services
  • Recurring instabilities

Our aim:

We would like to work with you to investigate any technical issues at an early stage, before they cause or exacerbate any noticeable disruptions to your day-to-day operations.

Informed at an early stage: We will contact you before any abnormalities lead to noticeable limitations.

Technically verified: These notifications are based on quality deviations detected at your connection.

It’s easy to arrange: simply choose a suitable, free call-back time with our technical support team online.

Possible implications for your business

Depending on the connection and usage, a variation in quality may have different effects. This may include, amongst other things, the following areas:

  • Internet access
  • IP telephony
  • VPN / Site-to-site networking
  • Cloud applications
  • Cash register and payment systems
  • Office and home office workstations

What do I need to do now, and what is the procedure?
