Maintenance Bulletins

All times are 24 hour UTC format
2018-07-01: Scheduled Maintenance for 2018-06-12

We will be performing database maintenance from 11:00:00PM to 12:00:00PM UTC. There may be queue delays while tables are locks during the maintenance process.

2018-06-01: Scheduled Maintenance for 2018-06-13

We are planning to build on the work we did splitting our monolithic redis instance into more single task redis instances to improve responsiveness. This task will begin at approx 13:00:00 UTC and finish at 14:00:00 UTC. There may be significant (tens of seconds) delays in processing screenshots and some screenshots may not process during this time as we use Redis to queue requests to our backend screenshot processors.

2018-05-01: Scheduled Maintenance for 2018-05-08

We are planning to split our Redis instances from one large Redis cluster instance to smaller instances for speed improvements and to take mitigate the single threaded nature of Redis. This task will begin at approx 07:00:00 UTC and finish at 08:00:00 UTC. There may be significant (tens of seconds) delays in processing screenshots and some screenshots may not process during this time as we use Redis to queue requests to our backend screenshot processors.

2018-01-20: Scheduled Maintenance for 2018-02-16

We're planning to move our remaining ScreenshotsCloud infrastructure over to Google Cloud Platform permanently. We've been testing this move by allowing gradually larger percentages of requests into GCP and will perform the final changeover on the 16th Feb. Some downtime and intermittent high screenshot processing time may be expected between 08:00:00 UTC and 09:00:00 UTC. This change will allow us to handle high demand while maintaining low processing times for screenshots.

2017-11-25: Scheduled Maintenance for 2017-12-14

We will be performing maintenance on the queue infrastructure which serves jobs to our browser instances starting 2017-12-14 08:00:00 UTC and ending no later than 2017-12-14 08:30:00 during which time there will likely be delays in serving browser rendering requests in a timely manner. This maintenance period is to allow us to provide regular maintenance to the queue system.

2017-10-27: Scheduled Maintenance for 2017-11-04

We will be performing maintenance on the queue infrastructure which serves jobs to our browser instances starting 2017-11-04 18:00:00 UTC and ending no later than 2017-11-04 18:30:00 during which time there will likely be delays in serving browser rendering requests in a timely manner. This maintenance period should provide a minor increase in rendering performance.

2017-10-21: Scheduled Maintenance for 2017-10-28

We will be performing maintenance on our load balancer starting 2017-10-28 02:00:00 UTC and ending no later than 2017-10-28 02:30:00. We expect no delays in serving browser rendering requests during this maintenance period.

2017-10-01: Scheduled Maintenance for 2017-10-04

We will be performing a major performance upgrade of our browser rendering infrastructure on 2017-10-01 12:00:00 UTC and ending no later than 2017-10-01 12:30:00. We expect minor delays in serving browser rendering requests during this maintenance period. Rendering times should be substancially reduced after this maintenance period.
