Open BLD DNS: Our supporter is UptimeRobot
 
Hey, UptimeRobot it is a very good solution for on-line monitoring tasks. I'm using UptimeRobot over than 10 years for monitoring tasks by:
- Ping availability my Blog and Forum
- HTTP(S) availability and SSL expiry reminders
- Port(s) availability for Open BLD services
- Keyword checking on web-pages

Free plan allow using UptimeRobot with 5 min. interval with notifications to email.

Now, UptimeRobot helps to Open BLD Project to reduce checking intervals to 1 min and now you can checking Open BLD status on:
https://bld-status.sys-adm.in page.

On my own behalf, I express my deep gratitude to the UptimeRobot service, now the availability and stability of the Open BLD service has more monitoring than it was.
