【Important】Scheduled maintenance in early August

Dear Mackerel users,

Thank you for your continued support. I’m id:sugiyama88, Mackerel’s project manager.

Thanks to all of you, Mackerel has grown a lot. And in order to prepare for even further leaps forward in the future, we have decided to schedule some maintenance. The main objective of this maintenance will be performance and feature expansions of the time series database.

At the time of scheduled maintenance, we will put maximum effort into minimizing the impact as much as possible. We are making this announcement in advance because users may be affected. Additionally, the maintenance is scheduled to be divided into two stages.

This is an important measure in order to be able to continually offer a better service and we thank you for your understanding and cooperation.

Maintenance schedule and effects

August 7th, 2017 (Monday) 2:30 p.m. - 4:30 p.m. (JST)

Changes and requests

Maintenance #1

The IP address of mackerel.io will change. For customers who are subject to IP address restrictions, add the new IP address in addition to the current IP address to the transmission permission target by August 7th (Monday).

※Due to a possibility of roll backs after maintenance completion, we suggest allowing the current IP address to remain for a few months. We will make a separate announcement regarding deletion of the current IP address.

Current IP address

59.106.194.79/32
59.106.194.84/30

Maintenance #2

For customers who are subject to IP address restrictions, add the new IP address in addition to the current IP address to the transmission permission target by the day of maintenance (A separate announcement will be made).

In addition, since some variation is expected in URL external monitoring HTTP response times, users with strict settings should adjust threshold values after maintenance.
