In order to avoid the provision of such other services having a negative impact on the availability or general quality of
internet access services for end-users, sufficient capacity needs to be ensured.
Providers of electronic communications to the public, including providers of
internet access services, should, therefore, offer such other services, or conclude corresponding agreements with providers of content, applications or services facilitating such other services, only if the network capacity is sufficient for their provision in addition to any
internet access services provided. The provisions of this Regulation on the safeguarding of open internet access should not be circumvented by means of other services usable or offered as a replacement for
internet access services. However, the mere fact that corporate services such as virtual private networks might also give access to the internet should not result in them being considered to be a replacement of the
internet access services, provided that the provision of such access to the internet by a
provider of electronic communications to the public complies with Article 3(1) to (4) of this Regulation, and therefore cannot be considered to be a circumvention of those provisions. The provision of such services other than
internet access services should not be to the detriment of the availability and general quality of
internet access services for end-users. In mobile networks, traffic volumes in a given radio cell are more difficult to anticipate due to the varying number of active end-users, and for this reason an impact on the quality of
internet access services for end-users might occur in unforeseeable circumstances. In mobile networks, the general quality of
internet access services for end-users should not be deemed to incur a detriment where the aggregate negative impact of services other than
internet access services is unavoidable, minimal and limited to a short duration. National regulatory authorities should ensure that
providers of electronic communications to the public comply with that requirement. In this respect, national regulatory authorities should assess the impact on the availability and general quality of
internet access services by analysing, inter alia, quality of service parameters (such as latency, jitter, packet loss), the levels and effects of congestion in the network, actual versus advertised speeds, the performance of
internet access services as compared with services other than
internet access services, and quality as perceived by end-users.
