@Ariv, thank you for your reply. My app was working fine for about 2-3 years on 1&1 shared hosting. Its just now that push notifications stopped as Siberian requires php-cli 5.6 or higher. apart from push notifications, rest of features are working fine. 1&1 has 5.5 at moment. Though they are saying that they will be updating it soon. Meanwhile some one told me OVh has all features :https://www.ovh.ie/web-hosting/web-hosting-personal.xml
I have send them a query about it will definitely update here.
Thanks
