A New IP Block (in case you need to whitelist it)

Starting on 2016-09-14, we are adding a new IP block to the system.

The current IP blocks are still staying active and we’ll start to send requests from this new IP block too.

Here are the details:

IP Block: 63.143.42.240/28

which means that the IPs are:

  • 63.143.42.242
  • 63.143.42.243
  • 63.143.42.244
  • 63.143.42.245
  • 63.143.42.246
  • 63.143.42.247
  • 63.143.42.248
  • 63.143.42.249
  • 63.143.42.250
  • 63.143.42.251
  • 63.143.42.252

And, the up-to-date list of the IPs can always be found in different formats at: https://uptimerobot.com/locations.

    This is a great free tool. User interface still a bit rough but the functionality is superb and sure beats the more expensive paid sites! Like the HipChat / Slack Integrations! Great job!

    Hi, looks like media temple might be blocking some of these IPs again, we’ve been getting so many false positives the past few days. I saw this happened in 2014 or so. Can you contact them and get them to update their whitelist again or verify this is what’s going on, please?
