There are topic or "reviews" that claim that 000webhost.com is more down than up, that 000webhost.com has maximum of 70% or even less uptime etc...
000webhost.com guarantees at least 99% uptime!
So we have purchased paid website monitoring service from uptimerobot.com and added major services to monitor every minute (that should be more than enough to see the real situation).
It monitors http (port 80) access (you use 80 port to access your website) for all servers every minute from multiple locations worldwide. If any of these location fails, outage is counted. So it is very strict and accurate.
Our server status page is located at http://status.000webhost.com
Feel free to check it out
You'll know if there are issues they'll be highlighted
It gives uptime of all the monitors in place
Also the last downtime will be recorded as well
If you have any issues with your site check this page first, if any monitors are red - the issue is known of, being worked on and doesn't require users to create multiple threads
