Hello!
In Singapore complaints against the servers are sometimes treated blindly without giving us enough time to reply and therefore IP addresses are null routed. When this happens the unblocking procedure may take time. Additional problems have included IPv6 network and line problems. Such problems may occur now and then even in any good datacenter. If the servers keep failing the expectations, as your complaints suggest, we will dismiss them and search for an alternative. It's not so easy in Singapore for the high volume traffic we require, so the matter is not trivial. Anyway, we already operate both on Leaseweb and M247 datacenters in Singapore, so we already offer redundancy.
Kind regards
