A few airband WebSDR and KiwiSDR sites are up and running. These radios are especially good for tuning for specific frequencies or manually following flights. I have tried ACARS and VDL Mode 2 and was able to decode messages on the KiwiSDRs. It is a pretty slick way to enjoy aero listening for flights on three different continents.

The SDR in Russia has several frequencies blocked, in narrow slices. If you are unable to monitor a frequency because of this, there are no good remedies. HF is easier, as there is usually another SDR from which to stream. No so in this case; Krasnoarmeysk is the sole internet SDR for airband in that area. If you listen to any of the KiwiSDRs and get timed out, try again the next day. If you are geo blocked, evade the blockage by deleting your browser cookies and using a VPN or SSH tunnel for future to connections.

How to use this list:

Select a frequency by clicking a numbered button.
Click on a receiver location to open an SDR tab in your browser.
The list is short today; more will be added as they are found.

Since VHF propagation conditions vary with weather in the troposphere (temperature inversions), listen around and note which frequencies have weak signals and others which are always empty. You might catch a nice period of enhancement from time to time.

Please be a fair listener on the KiwiSDR radio servers, as they have limited slots for visitors. Excessive time on one frequency or opening multiple SDR tabs from the same site at once may cause site operators to block users or frequencies who draw too much bandwidth.
