Even with redundant servers in their network architecture Packet 8 seems over the last few days to have a problem keeping it up, as yesterday alone the Santa Clara company had two outages of the thirty minute variety, on top of an outage outage last week.
Like Vonage has claimed in the past, it was due to a "server" malfunction related to an upgrade. Packet 8 in an email reply to my questions said "upon further investigation, I (we-sic) learned that the recent Packet8 service outages were caused by a server malfunction brought on by a software glitch associated with the feature upgrade we are currently implementing. This problem has been resolved and we are adding new servers to the network tomorrow while also telling me they have redundancy in their network.
