Yes, although the first impression is what counts here.
When a website does not have DNS Anycast (Unicast), the DNS query is first sent to our DNS servers in Switzerland and responded to from there. The second time that a website is accessed, the DNS query is no longer responded to by our DNS servers. Instead, the response comes from the cache/temporary storage of the respective internet provider’s DNS server. This means that it may take a while to load the first time someone accesses your website. When they access it again later on, the response time is quicker. This is the case until the DNS server cache is refreshed. Once the cache is refreshed, the first query without Anycast once again takes longer, because it again has to travel the whole way (potentially from another country) to our DNS servers.
With DNS Anycast, this is no longer the case. The first query is sent to a DNS server that is physically located near the website user. As a result, the first query and therefore the first impression are much faster. Just like with the Unicast procedure, all additional DNS queries are responded to through the cache until the cache needs to be refreshed. However, thanks to DNS Anycast, this also is much faster.
