Where we fit in this plan is any router that is updated must be taken down for 3 hours or so, which makes traffic reroute to other routers so the network traffic continues. When such rerouting is done it usually is accompanied by a change in traffic speed because of the longer route and possible capacity issues with the new route. Furthermore if that router is very close to our servers it is possible no route is available and we will be "blacked out" while the update is taking place.
Our ISP plans on doing these ISP maintenances through February. Many of you may have noticed a network drop late January, that was the symptom that started the ISP investigation and plan to fix it before it happens again. Below are the known ISP maintenances that have the best chance of directly affecting our service availability.
- February 9 : 2am - 5am Possible Black out, and/or suboptimal routing (Latency)
- February 18: Midnight - 3am, at least 20 minutes of downtime when IDC network is rebooted
- February 21 : 2am - 5am Possible Black out, and/or suboptimal routing (Latency is assured)
- February 22 : 2am - 5am Our ISP is switching our network, which would be 90 minute downtime. We will be also performing certain network adjustments that will ensure the downtime will be the full 3 hours.
