Since August 11 22:00 UTC, there appears to be an outage at iFastNet’s main DNS servers. This means that iFastNet’s own domains (primarily ifastnet.com and it’s subdomains) are currently unreachable. The DNS servers for hosted websites are still working.
InfinityFree is largely unaffected by this outage, except for Softaculous: scriptinstall.rocks is also using the main DNS servers of iFastNet, and as such is unreachable at this time.
As far as I can tell, it’s impossible to install scripts with Softaculous right now while iFastNet is fixing their nameservers.
Update: it appears that the DNS were restored around August 12 19:00 UTC.
Also, some previous investigation turned out that it appears to have been a problem with the DNS glue records for the byethost.org domain. The ifastnet.org nameservers are themselves hosted on the byethost.org domain. So a problem with that single domain appears to have caused widespread problems among all the domains of iFastNet. As to what was the cause for these records to disappear, I don’t know.
