They're still taking downtime for this... Even if they're forced to have a no-VIP no-HA no-LB setup (seems insane to me) it should be much simpler to set the DNS TTL to a low value right before and switch it to the new IP after the new box comes up.
- BraveNewCurency 9y agoYes, this is a wonderful technical hack, but terrible as a business strategy. They are admitting that they don't have a good architecture that would make upgrades easy.
- lathiat 9y agoThat assumes they have control over the DNS. Sounds like they don't with many end customers.
- markatto 9y agoThey shouldn't be giving their customers a static IP, they should be giving them a 'customername.ourplatform.com' address that the customer can point a CNAME at.
- vidarh 9y agoThis was addressed in the article: There is a tendency within that industry of whitelisting API access etc. by source IP, so their customers do need static IPs not primarily for inbound traffic, but to be able to access the APIs they need. Now it's still stupid of them to not abstract that away from the individual customer servers but, but this issue isn't solved with cname's.
