Temporary Internet Outage

There will be a short internet outage tomorrow morning, October 12th, at 6:00 AM for maintenance. The outage should last around ten minutes.

Update: Internet Upgrade Delayed

Our internet service upgrade – scheduled for last night – has been delayed until next week after we encountered an unexpected problem.  We do not have a specific date/time for the next upgrade window, but I’ll post that here as soon as we’ve completed a conference call with the involved parties. 

What happened?

At 5:00 PM, ICCSD network administrators, working with Iowa Communications Network (ICN) and Lightedge Solutions engineers, switched our internet connection from our current 1Gb ICN connection to the new 3Gb ICN connection.  A component of this switch also includes moving from our current internally-managed Palo Alto firewall to a Lightedge-managed Fortinet firewall; staying on our existing Palo Alto hardware is not an option, as it cannot handle the 3Gb throughput required for the new connection. 

The internet connection worked properly, as did all but one of the mission critical services that we had previously identified as potential points of failure during the internet service upgrade.  One service, however – a VPN tunnel to a particular site – was not successfully brought online after implementation of the new firewall.  We attempted troubleshooting until the close of our announced upgrade window, but with no success were forced to revert to the previous settings and service.  

What should I expect moving forward?

As previously mentioned, we’ll be rescheduling the upgrade window as soon as possible, likely for next week.  We’ve already identified the steps necessary to solve the issue with the site that didn’t come up, and now need to coordinate availability on the part of ICN and Lightedge.  I’ll post a specific date/time as soon as we have one. 

Since the upgrade was not successful, I expect that internet performance issues will continue for the coming (approximately) week.  Our network administrators have been tuning quality-of-service settings over the past couple of weeks in order to prioritize critical or interruption-intolerant traffic, and will continue to do so in order to make the most of the 1Gb service we currently have.  

As mentioned in my previous post on this topic, we expect all internet performance problems to be immediately resolved following the successful upgrade to 3Gb service.  We appreciate your patience as we work through this process.  

Internet Service Upgrade 9/27/17

UPDATE: This upgrade was unsuccessful (details here); we’ll be rescheduling the upgrade for next week. 

Tonight is a big night for our internet service in the Iowa City Schools; a long-planned upgrade will take place beginning at 5:00 PM (on September 27th) that will expand our service from 1Gb bandwidth to 3Gb.  Here’s what you need to know:

Laptop Demo Schedule

As we approach the staff device replacement dates in May, we are bringing the two laptop options – the Dell 5480 laptop and the Dell 5289 convertible tablet – to each of the buildings so that staff can have the chance to take a look at them firsthand.  Check below for the date and time scheduled for your building.  For those who cannot make the time in your building, we’ve also added some drop-in dates at the ESC at the end of the schedule.   Continue reading Laptop Demo Schedule

In-Depth: Staff Device Replacement Plan and FAQ

One of the challenges of planning substantial technology deployment changes within a large district like ours is tied to the interactions between those various policies.  One of the major changes that we’re making, beginning next year, is to shorten the district’s technology replacement cycle from 6 years to 4 years.  Additionally, our current model calls for the replacement of 1/3 of technology within each building, every other year.   Continue reading In-Depth: Staff Device Replacement Plan and FAQ
