Fios performance

Except where noted, reported speeds for Fios are median speeds based on Verizon internal network testing during October 2019.+


High Speed Internet 
(DSL) performance

Our High Speed Internet service is provided over a copper network which is subject to performance variation due to a number of factors including distance from switching stations. Due to these performance variations, this service is sold as a range of expected speeds as opposed to a single value to provide clarity to our customers.

Results from the FCC’s Eighth Measuring Broadband America - Fixed Broadband Report show that Verizon’s High Speed Internet service typically delivers median speeds within the advertised range of expected speeds.+


Key definitions

  • Download speed refers to the speed of the connection when downloading information to your computer.
  • Upload speed refers to the speed of the connection when uploading data from your computer.
  • Latency is an expression of how much time it takes for a packet of data to get from one designated point to another. In the Measuring Broadband America study, latency was measured by sending a packet that is returned to the sender and the round-trip time is considered the latency.

+The actual performance of an individual customer's broadband service may vary based on technology, network traffic, and a number of other factors. The information above was derived from various tests and is provided for informational purposes only. It is intended to provide you with an indication of the speeds obtained during such network testing. These results may not be fully representative of each individual customer's experience, and did not include variables such as customer inside wiring and Wi-Fi networks, customer computer configurations, additional customer-generated traffic on the customer’s broadband connection, the performance to specific internet destinations that particular customers may be interested in, the performance of other internet-based content, applications and services, and other such factors.

*Data for Gigabit Connection based on internal network-based testing using User Datagram Protocol (UDP). Results for the other tiers shown above are based on internal network-based testing using Transmission Control Protocol (TCP).  UDP and TCP are two protocols used to send information between computers and other devices over the Internet. Results based on TCP testing may be lower than results obtained through UDP testing.    

**This service tier was not included in the FCC’s Eighth Measuring Broadband America report. The FCC’s 2012 study is the source of the data for the HSI 3.1-7 Mbps download / 0.384-0.768 Mbps upload tier. The data presented for the 7.1-15 Mbps download / 0.5-1 Mbps upload tier is based on Verizon lab testing. Lab testing simulated internet-based network activity in an access network environment.

What factors can cause my service to vary?

The Fios network is used to provide other services, including Fios Video on Demand (VOD). The capacity available for Fios Internet access service may be reduced temporarily during times of significant utilization of Fios VOD in a particular area, if you watch multiple VOD titles simultaneously, or due to other unusual events such as a network outage or failure.

Verizon Online’s internet services are typically configured to use dynamic host-control protocol (DHCP) to provide subscribers with use of an internet protocol address, which may be a publicly routable internet protocol address or a privately managed IP address utilizing CGN (Carrier Gateway NAT) technology. Your broadband router or modem employs network address translation (NAT) to assign additional addresses for use by devices within your home network.

Verizon Business

IP latency statistics

Verizon Business is constantly measuring the latency (speed) of core areas of its network using data collected by pings via the Internet Control Message Protocol (ICMP).

How is the data collected?

Data is collected from designated routers in key network hubs world-wide, in 5-minute intervals. Monthly latency and packet delivery statistics are derived from averaging all samples from the previous month.

SLA/VSAT statistics

Verizon Enterprise Solutions is constantly measuring the latency (speed) of core areas of its network using data collected by pings via the Internet Control Message Protocol (ICMP). How is the data collected?

  • Network Transit Delay is the round trip average monthly delay between the origination and the destination between the in-route and out-route demarcation points.
  • Network Packet Guarantee is measured based on the percentage of test packets that reach their intended destination, divided by the total number of test packets sent.

Private IP network SLA statistics

Verizon Enterprise Solutions is constantly measuring the performance metrics of its Private IP network utilizing a variety of tools.

How is the data collected?

  • US Network Delay is calculated by measuring round trip transit delay between Verizon Enterprise Solutions-designated backbone network nodes across the contiguous US PIP Network and averaging the results over a thirty day period.
  • Network MOS is calculated by sampling performance scores for the EF traffic class, using the standards based E-model (ITU-T G.107), between Verizon Enterprise Solutions-designated backbone network nodes in each specific region and averaging the results over a thirty day period.

Verizon Business Internet network performance metrics, including backbone measurements on latency, jitter, packet-loss, and others, are available online.

Why services may vary.

Verizon Business offers a wide variety of other IP-based services, which share the Verizon Business network infrastructure with our broadband internet access services. With respect to these IP-based services, Verizon Business also engages in industry standard practices pertaining to capacity planning, network routing actions and failover activities. Despite these practices, there is a possibility that use of these services by you or other Verizon Business customers may affect the performance of your other services.

Verizon Wireless

Mobile service and fixed wireless

Based on our internal testing and testing commissioned from third-party vendors, Verizon expects customers will experience the following speeds unless such speeds are otherwise managed through video optimization practices described below:


* Depending on location, max speeds up to 940 Mbps. 4G LTE backup.
** With peak speeds of nearly 1 Gbps.
*** Video speeds may be slower depending on video resolution provided.

Verizon Wireless has used sound engineering principles in the design and operation of its broadband network to ensure a good user experience for all customers. An individual user’s experience will vary depending upon many factors, including the network (3G Ev-DO, or 4G LTE, or 5G UWB) the customer is using and the device in use. Verizon Wireless has implemented optimization technologies across its 4G LTE network to transmit data files in a more efficient manner to allow available network capacity to benefit the greatest number of users. These techniques include TCP optimization, video caching, and sizing video files more appropriately for mobile devices. The optimization process is agnostic as to the content itself and to the website that provides it. While Verizon Wireless invests much effort to avoid changing text, image, and video files in the optimization process and while any change to the file is likely to be indiscernible, the optimization process may minimally impact the appearance of the file as displayed on a customer's device.

In addition, in order to optimize customers’ video viewing experiences on their devices over our 4G LTE network while ensuring a high quality experience for other users of the network, Verizon seeks to transmit video downloads or streams to smartphones at 720p and to devices with larger screens at 1080p, unless a different video resolution is disclosed in the description of a particular plan. This practice does not make any distinction based on the content of the video or the source website. To achieve this optimization, Verizon limits the throughput speeds of such video downloads or streams over our 4G LTE network;(which may be below the 5-12 Mbps 4G LTE download speeds typically provided). This practice results in the video provider’s content server sending the appropriate resolution video file for that speed, if available.

For 4G and 3G coverage information, see the Verizon Wireless Coverage Locator

With respect to latency for use of real-time data applications, Verizon Wireless expects network to device (round-trip) latency to be less than 30 ms on its 5G UWB network, less than 100 ms on its 4G LTE network, less than 30 ms for LTE Home Internet, and less than 240 ms on its 3G Ev-DO network.

You must be using an approved, network compatible device and be within the Verizon coverage area to access the Verizon network. Whether you experience these speeds depends on many factors, including among others, the type of device, the programs running on the device, your location, and how many other customers are attempting to use the same spectrum resources (including both mobile broadband internet access and other non-broadband internet access services that share the network, such as Private Network Traffic Management, HD Voice, Push to Talk Plus, and MDM).

Why services may vary. 

An individual user’s experience will vary depending upon many factors, including the network (3G Ev-DO or 4G LTE) the customer is using and the device in use. On certain plans, we may prioritize your data behind other traffic. If the cell site you are connected to begins experiencing high demand during the duration of your session, your data speeds may be slower than the other traffic’s. Once the demand on the site lessens, or if you connect to a different site not experiencing high demand, your speed will return to normal. Any such network management practices will be disclosed in the descriptions of impacted plans.
