Field Scenario
A customer can access some websites but not others, and general internet connectivity otherwise seems to work fine.
What You Actually Do
- Consider DNS-specific issues as a genuine possibility given this particular symptom pattern
- Use this catalog’s DNS lookup tool to investigate whether the affected domains resolve correctly
- Recommend clearing DNS cache or trying an alternate DNS server as a practical troubleshooting step
- Explain to the customer why this differs from a general connectivity failure
