When will Microsoft Push Servers be fixed?

[anon(9650280)]

Any info about WP8.1 Push Server fix for Viber/Whatsapp/Skype/FB not being able to receive a call and notifications arriving late? The issue has been well known for months and widely reported for all Lumia phones.

The description makes it sound like it is wide-spread or is affecting the majority of Lumia phones (as a result of server-side failure) - but it isn't. The issue has been there, but only in isolated cases. Besides, the push notification service is usually limited by: 1) bandwidth; 2) signal quality (latency, packet loss); 3) phone memory. If the push notifications are to be resolved, these three factors must be looked into first.
