A cloud portfolio management provider has done some Monday-morning quarterbacking through cloud hosting customers affected by the recent Xen hypervisor problem and reboot for major cloud players.
If you go by Rightscale's numbers released today -- they surveyed about 449 customers of Amazon Web Services, Rackspace and SoftLayer -- Amazon seems to come out on top as the hosting companies worked to patch and reboot the potential issue announced Oct. 1.
Rightscale reported that of the 349 Amazon Web Services customers responding to Rightscale's Oct. 2-3 survey, 51 percent reported no application downtime as a result of the reboot, and another 21 percent reporting less than five minutes of downtime.
Of the 66 Rackspace Public Cloud users, 27 percent escaped with no downtime. Of the 42 SoftLayer Virtual Server respondents, 26 percent reported zero downtime.
Meanwhile, 5 percent of AWS users reported more than one hour of downtime, while 13 percent for Rackspace and 17 percent for SoftLayer said the same.
(Rightscale also received 74 responses from organizations that used Xen in their internal data centers. Some respondents use multiple clouds, hence the total of more than 449).
