The process of uploading videos using the File API is very slow

Gemini API

The process of uploading videos using the File API has suddenly become very slow. Previously, a 30-second video would upload successfully within a few seconds, but now it can take up to several tens of minutes. This issue has persisted for a few days. I have tried changing the API key, checked the network, and even had other people run it on different hosts, but the problem remains unresolved.
The code I am using is as follows:

video_file = self.gemini_client.files.upload(file=video_segment)
            while video_file.state.name == "PROCESSING":
                time.sleep(1)
                print(".", end="")
                video_file = self.gemini_client.files.get(name=video_file.name)
            
            contents = [
                types.Content(
                    role="user",
                    parts=[
                        types.Part.from_uri(
                            file_uri=video_file.uri,
                            mime_type=video_file.mime_type,
                        ),
                        types.Part.from_text(text=input_prompt),
                    ],
                ),
            ]

            for attempt in range(3):
                try:
                    response = self.gemini_client.models.generate_content(
                        model=self.gemini_model_version,
                        contents=contents,
                        config={
                            'response_mime_type': 'application/json',
                            'response_schema': Output,
                        },
                    )
                    break
                except errors.ServerError as e:
                    print(e.code)
                    print(e.message)
                    wait_time = 2 ** attempt
                    print(f"Attempt {attempt+1}/3: 503 error. Retrying in {wait_time}s...")
                    time.sleep(wait_time)
                except Exception as e:
                    print(f"Fatal error: {str(e)}")
                    raise

After checking the output, a large number of “.” appears after each video upload.
