A failure in an underlying cloud provider was causing elevated errors and latency in PubNub's European point-of-presence. They routed traffic around the errors while the issues persisted and the issues have now been corrected. We are currently monitoring traffic to ensure there are no other issues.
Due to a data center failure of one of PubNub’s cloud infrastructure providers, they experienced higher than usual latencies across all of their services in their Europe point-of-presence from 7:06 am EST to 7:55 am EST. They routed traffic around these issues to minimize latency and impact while the provider rectified its issues. Once the infrastructure was stable, they were able to return traffic to its normal flow.
While we received alerts on the backend of this issue, there were no discernible issues affecting the Kustomer application. Clients may have experienced brief issues with chat connectivity during this time but this was not reported to us.
