Yesterday there was a connection problem between us and GrubHub related to the infrastructure on our partner’s side. Because of this, we observed orders not being processed within 15 minutes. After this, the connection was restored, but we accumulated a large queue of requests, which exceeded the GrubHub's limit. Some orders may not have arrived because of this. Also because of this, authorization to GrubHub stopped working. We solved the problem with orders in 2 hours, while authorization will be resolved today
