League of Legends EU West high ping after 10pm: how to tell if ISP or server

Part of our guide on how to fix night packet loss

Identify whether your League of Legends EU West high ping after 10pm comes from your home network, your ISP’s evening congestion, or Riot’s servers using the exact hostnames and step-by-step tests provided.

Common causes of League of Legends high ping on EU West after 10pm

Three places cause spikes after 10pm: your home network, your ISP under evening peak load, and Riot’s EU West servers. Test each in that order. Test the easiest local fixes first. If local fixes fail, move outward along the connection path.

Wi-Fi interference, many devices on the same router, or an underpowered router increase ping at night. Those issues act inside your home and show up on a simple wired-versus-wireless test.

ISPs carry more traffic in the evening. That usually runs from 8pm to midnight. When more people stream, game, or video chat, the shared parts of your ISP’s network get crowded. Crowded links and busy routing nodes add latency and packet loss. The exact delay and timing vary with your ISP and neighborhood.

Riot’s EU West cluster can also see higher load after 8pm. Game servers, matchmaking, or maintenance windows can raise response time. You can confirm that using Riot’s status page and traceroutes to EU West hosts. We go through na league server status keeps disconnecting me step by step elsewhere on the site.

Routers that are older than four to five years sometimes fail to handle modern simultaneous streams. Firmware bugs also add latency at particular times when traffic patterns change. Update router firmware and check CPU or memory use on the device when you see spikes.

• Local network: Wi-Fi signal, device count, outdated router firmware
• ISP peak traffic: heavier use from 8pm to midnight can raise latency on shared links
• Riot server load: high player counts or maintenance can increase response times

Why ping often jumps after 10pm on EU West

Evening hours of 8pm to midnight concentrate household internet use. Families stream shows. Gamers join matches. Video calls and cloud backups run more often. Those combined loads stress the shared parts of ISP networks.

Traffic changes can push your packets through different routing nodes. If routing shifts to an oversubscribed node, your ping jumps. That routing change can happen when many customers join the network at the same time. For the detail, see our notes on kr server lag in league after switching regions.

Riot’s EU West region draws more players in the evening. More players mean more requests and sometimes slightly slower responses. If Riot runs maintenance or moves traffic between data centers at night, latency can rise for a while.

Some ISPs also use traffic management rules in evening hours. Those rules can reduce throughput for certain types of traffic or change priority, which affects gaming packets more than standard web browsing.

Your exact pattern depends on your ISP, your local network, and where your home sits in the ISP’s topology. One ISP in your city may show a clear 8pm to midnight spike. Another ISP on the same street may not. Test on multiple nights to find a pattern. It helps to understand ping spikes in league before going further.

What hostnames and IPs to test for EU West

You need concrete hostnames or IPs to ping and traceroute. Riot uses multiple endpoints. The Riot API and some game services use named endpoints under riotgames.com. Use those names to resolve the current IPs your network sees.

Try these hostnames first. They point to Riot-related infrastructure used in EU West testing: euw1.api.riotgames.com, prod.euw1.lol.riotgames.com, and l3cdn.riotgames.com. Resolve each name on your machine to get the IP address your DNS returns that day. That IP is what you traceroute to.

Do not expect a single static IP to represent all EU West servers. Riot uses many IPs and cloud front ends. The hostname-to-IP mapping can change. The goal is to reach the same resolved IP when you compare tests over time. For the detail, see our notes on identifying lag causes in league.

If you prefer direct examples, run a DNS lookup now and use the IP you get for traceroute. Example commands appear below and show how to get current IPs from those hostnames. Use the exact IP shown in your lookup for consistent comparison across tests.

If one of the listed hostnames fails to resolve, try the others. If none resolve, check Riot’s status page or your DNS settings.

How to find Riot’s official server status page

Open your browser and go to https://status.riotgames.com. That is Riot’s official status site. The site lists the main Riot services and their current status. Before you commit to anything, it is worth looking at fps issues in league update.

To see EU West details, choose the region or look for entries mentioning League of Legends or EUW. The page shows incidents, maintenance notes, and timestamps so you know whether a reported issue coincides with your ping spikes.

If you want community reports, check Riot’s official Twitter account for status updates or the League of Legends technical support pages. Use only Riot's official status page for verified maintenance notices and outage details.

Save https://status.riotgames.com to your bookmarks. Check it before you test at night. If Riot reports an incident in EUW, your traceroute will likely show high latency near the final hops.

How to find the EU West server IP or hostname used by your game client

While a match runs, you can capture the server connection details your client uses. Two reliable methods work on Windows.

Method 1. Use netstat. Open Command Prompt with admin rights. Run: netstat -n | findstr :2099 or netstat -n | findstr ESTABLISHED. Look for remote IPs connected to the Riot client. Note the IP and use it in a ping or traceroute test.

Method 2. Check the Riot client logs. Open the Logs folder in your League installation directory. Look in logs/Network or logs/Match for entries that show server IPs or hostnames. The log lines give the exact server you connected to for that match.

If you cannot find logs or netstat entries, run Wireshark for a short capture during match start. Filter for TCP or UDP traffic from your client. The capture shows the remote IP. Use that IP in traceroute tests. Only capture a few seconds to protect your bandwidth and privacy.

Once you have the IP or hostname, run the traceroute commands below to see where latency rises. Compare results for wired and wireless runs and for different times of night.

Step-by-step network tests to isolate the source of high ping

Follow the three tests in order. They escalate from local checks to ISP-level checks and finally to server-side checks. Run them both before 10pm and after 10pm so you compare results.

Step A. Wired vs Wireless test. Connect the PC by Ethernet directly to the router. Close background apps. Ping a resolved EU West hostname (resolve each hostname first). Note average ping and packet loss. Then switch to Wi-Fi and repeat. If Ethernet improves ping by a consistent margin, fix the Wi-Fi.

Step B. Traceroute to the EU West hostname or the resolved IP you found in logs. Windows command: tracert <hostname_or_IP>. macOS/Linux command: traceroute <hostname_or_IP>. Look for the first hop that shows a big jump in latency or packet loss. Early hop spikes mean your router or ISP. Late hop spikes close to the destination mean Riot-side issues.

Step C. Compare traceroute to a general internet endpoint. Use a neutral hostname like 1.1.1.1 or 8.8.8.8. If both traces show similar late-hop latency, the problem is higher on your ISP’s path. If only the Riot trace shows late-hop spikes, Riot or its transit partners are the likely cause.

Run each test at 9pm and at 11pm on the same day. If you see repeated higher latency after 10pm at the same hop, that hop is the likely bottleneck during evening peak hours.

Document the hop numbers and timestamps. That information helps when you contact your ISP or post a support ticket to Riot.

1. Connect PC via Ethernet cable and resolve the EU West hostname you will test (nslookup euw1.api.riotgames.com).
2. Ping the resolved IP: ping <IP> -n 30 on Windows or ping -c 30 <IP> on macOS/Linux. Record average latency and packet loss.
3. Run traceroute: tracert <IP> on Windows or traceroute <IP> on macOS/Linux. Note hops with >100 ms or packet loss.
4. Repeat the ping and traceroute on Wi-Fi and at a later time (for example 9pm and 11pm).

How to read traceroute results and act on them

If the large latency jump appears at hops 1 to 3, fix your router or home network. Update firmware, replace the cable, or change the router if it sits near CPU or memory limits during peak traffic.

If the spike appears in mid-path hops owned by your ISP, collect timestamps and traceroute outputs and contact the ISP. Ask them to investigate the congested node. Provide the hop IPs and times you recorded.

If the spike occurs in the final hops that resolve to Riot hostnames or to an IP that resolves from a Riot hostname, check Riot’s status page. If Riot reports an incident, wait for their update or open a ticket with the session logs.

If mid-path hops belong to a transit provider, moving to a different ISP or using a routing booster that provides alternative paths can help. Test a booster on the free trial and compare traceroute outputs before and after to see if the path changes.

Keep a log of before and after traces. A clear pattern helps both ISPs and Riot’s support staff act faster.

Practical fixes for stable ping after 10pm on EU West

Use Ethernet for competitive play. It removes Wi-Fi variables and gives the cleanest test results.

Pause large downloads and uploads during your session. Bandwidth hogs cause queuing that increases ping.

Turn on router Quality of Service and prioritize game traffic or your PC’s IP. That reduces queuing inside your network.

Update router firmware and replace routers older than four to five years. Newer hardware handles many simultaneous connections better.

If traceroute repeatedly points to your ISP’s nodes, open a ticket. Give them the times and traceroute outputs. Ask if they see congestion on the specified nodes between 8pm and midnight.

If your ISP cannot fix route congestion, test a routing booster or try switching DNS to a fast resolver like 1.1.1.1 or 8.8.8.8. Measure results before you purchase any service.

• Prefer Ethernet over Wi-Fi for gaming
• Pause background uploads and downloads in late evenings
• Enable QoS on the router and prioritize the game client
• Document traceroutes and contact your ISP when mid-path hops show persistent spikes
