Disruption activity index (0–100). Published incidents and repeated check failures carry more weight than emerging problem patterns. This is not a report count or percentage of affected users. Gaps have no observations; connecting lines do not add measurements.

Observed disruption signals combine available incidents, recorded reports, website checks, and emerging problem patterns. A low score does not guarantee that every feature is working.

Latest observation: 2026-10-28 12:18:47 UTC. Refreshes automatically while this page is visible.

How to read this calendar

Dates use New York time (America/New_York). Green means no issues observed with sufficient monitoring coverage; it does not guarantee uninterrupted uptime. Pink includes official incidents, repeated website failures, or corroborated user reports. Gray days are unknown. Activity estimates alone do not turn a day pink. Today’s result can change.

BMO Harris Bank website uptime and response time

DNS lookup failed Last checked 2026-10-28 12:18:47 UTC.

Checked address: https://www.bmoharris.com/

DNS lookup: unknown ms · TCP connection: unknown ms · TLS handshake: unknown ms. Diagnostic: ENOTFOUND.

Median response time

Unknown
95th percentile response time

128 failed checks; 0 restricted checks. Restricted checks are excluded from the success rate. Lines connect recorded samples across gaps; availability between checks is unknown. Response time measures receipt of HTTP headers, not full page load. Checks run from one US monitoring server and do not verify sign-in, API, or app features. These sampled results are separate from down reports and estimated activity.

Evidence behind the status

Repeated website check failures. Two recent checks of the monitored website endpoint failed. This does not establish that the full app or API is down.

Website checks and estimated activity have independent update times. Refer to each section for its latest observation.

These measurements describe different things. A reachable homepage can coexist with login or API failures. Missing evidence stays unknown.

Official component status

No mapped official components are available for this product. Parent-company status is not substituted for product status.

Official incident timeline

No product-matched incidents are available in the collected provider history. This does not prove that no incident occurred.

Recovery tracker

No recent recovery can be established from available evidence.

0 consecutive successful checks within the last 30 minutes. These checks measure the public website; they cannot establish recovery of every feature.

Slowdown detection

More successful checks are needed to establish a response-time baseline.

Recent median: unknown · Earlier median: unknown. Flags require at least 3 recent and 5 earlier checks, more than twice the baseline, and at least 500 ms extra latency. Slowness alone does not identify server load as the cause.

Emerging down-report signals

No recent emerging problem patterns are available for this service.

Emerging problem patterns can persist after an incident and do not measure report counts or prove an outage.

Is it down in your region?

Run one public website check from a community probe. Results describe that probe, not every user in a country.

Results are reused for 15 minutes. Shared free allowance: up to 60 tests per hour. A successful website check does not verify authenticated app or API functions.

Infrastructure incident context

Check whether broader platform incidents coincide with the problem you are seeing. These providers are context, not verified dependencies of BMO Harris Bank.
