Azerbaijan has announced the replacement of cryptographic keys that serve as protection for domain name systems (DNS). Cryptographic keys, first introduced in 2010, are responsible for the security and integrity of internet addresses. In Azerbaijan, this is for websites that end in “.az”, including those ending in “.com.az” and “.edu.az”.
Website users generally experience minimal interruptions when such a change occurs; however, a small percentage sometimes faces difficulties in accessing some websites. The most common issues is usually users receiving messages about an inability to access a website (i.e. a “server failure” (SERVFAIL) error). This generally lasts no longer than 48 hours.
