[fr-par-1] Latencies spikes during the day following capacity increase in one of block storage cluster

0

Scaleway Block Storage has latency spikes in the fr-par-1 region. This degrades Block Storage, Databases, and Instances. Scaleway identified the problem and applies a fix rack by rack. Data must be removed first, so migrations run slowly and continue through the weekend.

The fix improved nvme behavior during the day and today we applied it on half of the concerned rack. As data must be removed first to apply the fix, migrations operations are processing slowly to avoid worsening impact on latencies. Migration operations will continue through the week-end.

Your coding agent knows when Scaleway is down, and tells you when a failure is theirs, not yours. You can also get Scaleway incidents in a feed reader or in Slack.

Prompt
Install the outages.live MCP server, so that when something breaks you can tell if the cause is a provider we depend on and not my code. It reads the official status pages of cloud, AI, payment and developer providers and gives you their incidents as MCP tools.

Add it as a remote MCP server named "outages" at https://outages.cc/mcp (Streamable HTTP, no authentication), with your CLI command or your MCP config file.

Then:
1. Make sure it connects and shows the tools get_provider, list_feed and send_feedback.
2. Call get_provider with "scaleway" and tell me if Scaleway has a problem right now.
3. From now on, when a call to a third-party service fails or becomes slow, call get_provider for that service before you change my code.

Paste this into any coding agent. It adds the server with its own MCP setup.
