Is A1 Throttling Your Speed? The “Strange” DNS Bug Hitting Austria This Week and How to Bypass It for Faster Browsing

We are currently tracking credible reports from A1 Telekom Austria subscribers experiencing sporadic connectivity failures as of November 19, 2025. While the physical internet connection (DSL/Fiber/5G) appears stable, users are facing a DNS (Domain Name System) resolution failure, effectively locking them out of major services like X (formerly Twitter), Salesforce, and Google properties.

The Symptoms

Affected users report a “partial outage” scenario that can be confusing to diagnose.

  • Selective Inaccessibility: Some websites load perfectly, while others (specifically business tools like Salesforce or social platforms like X) time out or fail to resolve.
  • Browser Errors: You may see errors such as DNS_PROBE_FINISHED_NXDOMAIN or “Server Not Found.”
  • Downdetector Spikes: Recent data correlates these individual reports with a visible spike in outage flags for major services, suggesting the issue lies with the “road” (the ISP), not the “destination” (the websites).

Technical Analysis: Why is this happening?

Based on the behavior reported—where switching DNS providers immediately resolves the issue—the root cause is almost certainly a malfunction within A1’s default DNS servers.

Think of a DNS server as the internet’s phonebook. When you type google.com, your ISP’s phonebook (DNS) looks up the IP address. Currently, A1’s phonebook appears to be missing pages or responding too slowly.

  • The Fix Works: Users confirming that switching to Cloudflare (1.1.1.1) or Google Public DNS (8.8.8.8) restores full access proves the underlying internet pipe is healthy; only the “directory service” is broken.
  • Context: This incident follows a significant global fluctuation in internet traffic observed on November 18, which may have caused caching errors or upstream routing instabilities for regional ISPs like A1.

Immediate Workaround: Change Your DNS

If you are an A1 customer facing these issues, you do not need to wait for a technician. You can bypass the faulty A1 servers immediately by changing your DNS settings to a reliable third-party provider.

Recommended Public DNS Servers:

  • Cloudflare: Primary 1.1.1.1, Secondary 1.0.0.1 (Focus on privacy and speed)
  • Google: Primary 8.8.8.8, Secondary 8.8.4.4 (Focus on reliability)

How to change it (Windows 10/11):

  1. Open Settings > Network & Internet.
  2. Select Wi-Fi or Ethernet (whichever you are using).
  3. Click on “Edit” next to “DNS server assignment.”
  4. Switch from Automatic (DHCP) to Manual.
  5. Toggle IPv4 to “On” and enter the Preferred DNS (e.g., 1.1.1.1) and Alternate DNS (e.g., 1.0.0.1).
  6. Click Save.
