This month, some Bonsai customers were impacted by networking problems in AWS’ Oregon region. Our services were not impacted internally, however customers in our Oregon region had issues resolving hostnames and connecting to their clusters. There was also a period of scheduled maintenance in upgrading all customers from Elasticsearch 1.3 to 1.4, which went smoothly for the most part. There have been some unexpected growing pains with 1.4, but we have more or less worked out the kinks.
For these reasons, we’re reporting our March 2015 availability as 99.991%. We expect that this should improve over the next month as system loads are rebalanced.
For further information on how we think about and report our availability, see our article on Measuring Availability as an Elasticsearch Hosting Provider.
