Hi blipper!
On 09/08/2021, Wednesday, we faced an unavailability on Blip that affected the operation of many Smart Contacts.
To be transparent with you, Blip user, we are writing to tell you what happened.
What happened
A failure in connection with our cache service was identified, which is used to store contact information, causing an interruption in the exchange of messages from our smart contacts.
How this issue impact you
Because of this failure, the Blip CRM, our customer base management functionality, faced problems in executing message exchanges.
In the name of Take Blip, I want to say sorry for any problems caused to you, your company and your customers.

As soon as we identified the problem at 8pm -3UTC, our team put together and acted quickly to start the treatments. The correction was immediately applied and the service was normalized at 10:36pm -3UTC.
Where we are now
The Blip CRM is working again, and our technical team is following up with the cloud provider to identify the main cause of the failure. In addition, we have internal actions to prevent events like that again.
