Are websites and social media apps blocked? Is your network unusually slow? Run OONI Probe to find out! With this app, you will examine the blocking of websites and instant messaging apps, measure your network's speed and performance, and check whether systems that could be responsible for censorship and surveillance are in your network. OONI Probe is developed by the Open Observatory of Network Interference (OONI), a free software project (under The Tor Project) that aims to uncover internet censorship around the world. Since 2012, OONI’s global community has collected millions of network measurements from more than 200 countries, shedding light on multiple cases of network interference. ▶ Collect evidence of internet censorship You can check whether and how websites and instant messaging apps are blocked. The network measurement data you will collect may serve as evidence of internet censorship. ▶ Detect systems responsible for censorship and surveillance OONI Probe tests are also designed to uncover the presence of systems (middleboxes) that could be responsible for censorship and surveillance. ▶ Measure the speed and performance of your network You can measure the speed and performance of your network by running OONI's implementation of the Network Diagnostic Test (NDT). You can also measure video streaming performance with the Dynamic Adaptive Streaming over HTTP (DASH) test. ▶ Open data OONI publishes network measurement data because open data allows third parties to verify OONI findings, conduct independent studies, and answer other research questions. Openly publishing OONI data also helps increase transparency of internet censorship around the world. You can explore and download OONI data here: https://ooni.io/data/ ▶ Free software All OONI Probe tests (including our NDT and DASH implementations), are based on free and open source software. You can find OONI software projects on GitHub: https://github.com/ooni. Curious to learn how OONI Probe tests work?

Compare electricity and natural gas rates across Pennsylvania and switch to a cheaper energy supplier — GridScout PA does the shopping for you. It pulls rates straight from the Pennsylvania Public Utility Commission's official sites, PAPowerSwitch and PAGasSwitch, and instantly shows the lowest fixed-rate electric and gas supplier for your utility. Pennsylvania has energy choice: your market is deregulated, so you can pick who supplies your electricity and gas — often at a lower rate than your utility's default "Price to Compare." But comparing dozens of electric and gas offers by hand is slow. GridScout PA compares energy rates for you in seconds and helps you save on your electric and gas bill. WHAT YOU GET - Your utility's current Price to Compare (PTC) — the benchmark every supplier offer is measured against - The best fixed-rate electricity and gas offer for your utility, with the rate, term length, cancellation fee, and any monthly fee - Filters for Best Value, No Fees, and contract length - A one-tap "Sign up" link that opens the supplier's enrollment page for that exact offer - A home-screen widget with your utility's latest rate COMPARE ELECTRIC RATES FROM PECO Energy, PPL Electric Utilities, Duquesne Light, Met-Ed, Penelec, Penn Power, and West Penn Power. COMPARE NATURAL GAS RATES FROM Columbia Gas of Pennsylvania, PECO Gas, Peoples Natural Gas, UGI, National Fuel Gas, and Philadelphia Gas Works (PGW). WHY FIXED RATES GridScout PA shows fixed-rate plans only. Variable "teaser" rates can look cheap at first, then jump after a month or two — a fixed-rate electricity or gas plan locks in your price for the whole contract, with no surprises. STRAIGHT FROM THE SOURCE Every rate comes from the PUC's own Apples to Apples data — the same numbers you'd see shopping on PAPowerSwitch.com or PAGasSwitch.com — refreshed regularly so you're always comparing current offers. Switching electricity or gas suppliers is free, doesn't interrupt your service, and your utility still delivers the energy and handles billing. GridScout PA just helps you find the cheapest energy supplier and enroll in a couple of taps. Whether you want to lower your electric bill, cut your gas bill, or just see if a better rate is out there, GridScout PA makes energy shopping in Pennsylvania fast and simple. GridScout PA is an independent app. It is not affiliated with, endorsed by, or sponsored by the Pennsylvania Public Utility Commission, any utility, or any energy supplier. Rates are subject to change; always confirm the current price and terms with the supplier before enrolling.
