Multi-Datacenter High Availability for SetCronJob

Hello there,

After recent incidents with the datacenter SetCronJob hosted in, I decided to move all the main servers to another data center as well as work on multi-datacenter clustering.

The servers transfer and multi-datacenter setup were completed without any service downtime. Now SetCronJob fully achieved high availability that can withstand whole datacenter outages.

The clustering was done with great help from Clustermin, my developing service for server cluster management and automation. Setting up once and it'll run setup script, update firewall rules and configurations files in all servers and all clusters, whenever a new server is added or old server removed.

The current setup will greatly improve our service reliability, and hopefully, I don't need to inform you about any downtime again ;-)

Power outage in our data center

Hello all,

I'm sorry to inform that we had another power outage at our new datacenter (we migrated to another data center after the last incident). Because of it, our service was unavailable from 22:56 to 23:55:30 July 18, UTC time.

The service has been working fine since then.

I'm still working on our server clusters to prevent this from happening again.

Sorry for the inconvenience that caused.

If you encounter any problem with our service, just let me know.

Connectivity issues in our datacenter

Hello there,

Currently, our server provider has a problem with their datacenter in Fremont which SetCronJob hosts on. The whole service is down at the moment.

UPDATED: SetCronJob is online and working again. The total service downtime is about 2 hours 50 minutes.

Although I had no control over major issues like this, I relied too much on my server provider and didn't react in time to migrate the databases to another data centers. This cause unnecessarily longer downtime of the service.

As a token of our apology, I have added a credit of 10% of your account plan price (e.g. $5 for Platinum accounts) to your account balance.

If you have any question or encounter any problem with SetCronJob, please feel free to let me know.

View predicted/scheduled cron execution times

Hello all,

You can now view your cronjobs' scheduled/predicted execution times at Logs > Scheduled executions. We'll calculate minimum 10 executions, maximum 150 executions OR 1 day.

For example, a cronjob running daily, at random time (hour and minute) will have 10 scheduled executions as shown below:

A cronjob running every 10 minutes will have predicted executions as shown below:
The scheduled executions will be calculated every time you create, update, enable cronjobs. A scheduled execution will be removed each time your cronjob is executed.

It'll help you get a better understanding of your time settings.
