DNS time-to-live

What you might see or experience

Your application occasionally loses connection to Avalara services.
DNS lookups return outdated IP addresses.
AvaTax or related APIs stop working after Avalara updates DNS records.

Why this happened

Some software doesn’t correctly handle DNS time-to-live (TTL) values. This causes it to cacheold IP addresses instead of refreshing them when Avalara updates its DNSrecords.

What might help

Steps

Try the following:

Ensure your software respects DNS TTL values and periodically refreshesits DNS lookups.
Verify that your software or environment contacts DNS regularlyto update name resolutions.
Update your software if needed. Some versions, especially certain JavaJRE releases, may not handle TTL values correctly.
If problems continue after DNS updates, check the documentation for youroperating system, programming language, or developmentenvironment to confirm it handles TTL values properly.
