Maximizing Internet/Network Performance

While we’ve taken many steps to expand our network access and performance over the past few months, the reality is that all networks face hard limits in terms of the amount of data that can be moved at once.  

In order to ensure that teachers and students are able to maximize internet and network performance, here are a few useful tips: Continue reading Maximizing Internet/Network Performance

Network Outage Late Afternoon (Hills, Weber, Transitions)

Due to an emergency router replacement, the wired and wireless networks at Hills, Transitions, and Weber will experience outages today beginning at 5:00 PM.  This will impact ability to use the internet, access network resources, connect to the ICCSD wireless network, and use phones from those buildings. 

We expect that the outage will last for approximately one hour.  We appreciate your patience as we undertake this work. 

Progress is Messy!

As Labor Day passes, we’re beginning the third week of the school year in Iowa City and really starting to roll towards 2018.  While this time of year is always ridiculously busy for the Technology & Innovation office – it’s not uncommon in our district and others to see support requests come in at five to six times the normal rate during the first month or so of the school year – this year has been our craziest yet.   Continue reading Progress is Messy!

Brief Network Outage on August 28th

As part of a planned system upgrade, the ICCSD internet connection will briefly be offline at 5:00 PM on Monday, August 28th.  We expect this outage to last for a short time, but there is the possibility that outages will continue either continuously or sporadically for up to one hour.  

We do not expect any downtime after 6:00 PM on August 28th.  As always, we appreciate your patience as we work to improve our network infrastructure and performance. 

What’s New in the Technology & Innovation Department: E-Rate

With temperatures in the 50s this past weekend, it finally seems as though spring is in sight.  While day-to-day technology support needs in the district tend to hit a bit of a lull at this time of year – many chronic issues have been solved, and most new technology initiatives and programs are well-established – this is a busy time of year from a planning perspective. Continue reading What’s New in the Technology & Innovation Department: E-Rate

Upcoming Network Infrastructure Upgrades

While I’ve written about this a bit before in a broader sense, I wanted to share some information about the network infrastructure and core upgrades that we’ll be implementing in the coming months. Continue reading Upcoming Network Infrastructure Upgrades

Bottlenecks, bottlenecks, bottlenecks!

break_the_bottlenecks_with_ideas-_use_the_suggestion_box_-_nara_-_534150Let me start this post by saying that as a technology professional, I hate bottlenecks.

In saying as much, I’m probably preaching to the choir; almost ALL of us struggle with bottlenecks in our daily lives.  Traffic jams are usually caused by a bottleneck – the reduction of lanes from 4 to 2, for instance – that results in more traffic per available lane.  bottleneck-trafficSince two cars cannot peacefully occupy the same space on the road, a reduction in lanes during a heavy traffic period means that fewer cars can move through that obstructed zone at a time, resulting in a backup as faster-moving traffic piles up behind the slower-moving obstructed zone.   Continue reading Bottlenecks, bottlenecks, bottlenecks!

Resolved: ICCSD Experiencing Network/Internet Disruption

*UPDATE: 1:21 PM, 10/28/16*
Normal internet and network operation has now been restored district-wide.  We identified a network policy that was creating an inordinate amount of traffic.  That traffic flow has now been stopped, and other network indicators are now within normal ranges.  We appreciate your patience as we worked through this problem.   

8:00 AM: The ICCSD network is currently experiencing a networking / internet service disruption as of 8 AM on October 28th.  

speedtest_102816This can be seen in the image at the right; typically an early-morning speed test should show between 500Mb and 1000Mb down; currently I’m seeing 5Mb down from my test machine.  While the internet is still accessible, performance – especially for streaming applications – will be slow and/or unreliable until the problem is resolved.  

We believe that we have isolated the issue and are working to fix the problem.  I will provide an update here as soon as the problem is resolved.  We appreciate your patience in the meantime.
