What domain do you use? Recently we found some news (surprisingly not spread enough before) about using .IO domain issues. On September 2017 it was a big outage happened to about 20% of DNS resolutions for all .io domains. They were totally broken. So you’d better be aware of .IO domain name reliability issues.
.IO domain is not a great choice anymore. The outage on September 20th showed how severe the problems and support infrastructure are. Despite that it was hard to find people complaining about that, there were a lot of outages.
If you already use this domain please make sure you consider:
- Adding a backup .ORG domain name
- Using a backup DNS provider for either the .COM or .ORG domain name
- Implementing client-side DNS failover in our SDKs
