## Updates from DatoCMS
### 2023-05-01 17:34 UTC: resolved
Resolved — A fix has been implemented by Fastly
 Identified — We have received reports from our customers of failing builds on Vercel with error 502 I/O Error while performing requests to graphql.datocms.com
 It looks like that our CDN provider (Fastly) has an open issue related to the San Jose California datacenter: https://www.fastlystatus.com/incident/375837 
 Since Vercel is building your projects from San Francisco, it's very likely that they will end to the San Jose California (SJC) Fastly datacenter.
 This is not related to Vercel. You might get these errors if you build your project in California.
