Vandrovnik 215 Posted February 3, 2020 Hello, is there a way how to report to Embarcadero, that https://quality.embarcadero.com/ is down (again)? Share this post Link to post
Vandrovnik 215 Posted February 3, 2020 Hmm, on another PC, it works, too. There is nslookup quality.embarcadero.com = 204.61.221.78 On my PC, quality.embarcadero.com resolves to 204.216.225.148, which does not work... Â Share this post Link to post
Vandrovnik 215 Posted February 3, 2020 Hmm, it seems embarcadero is using TTL 3 days (!) for that record, so if they did change the address recently, it is still in the caching DNS.  # dig quality.embarcadero.com @ns1.navidns.net ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.68.rc1.el6_10.3 <<>> quality.embarcadero.com @ns1.navidns.net ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 17856 ;; flags: qr aa rd; QUERY: 1, ANSWER: 1, AUTHORITY: 3, ADDITIONAL: 6 ;; WARNING: recursion requested but not available ;; QUESTION SECTION: ;quality.embarcadero.com.      IN     A ;; ANSWER SECTION:quality.embarcadero.com. 259200 IN     A      204.61.221.78  Share this post Link to post

Here is a description how to do it in a better way than just to change record with TTL 3 days: https://www.dnswatch.info/articles/dns-update  Share this post Link to post
